Evaluating powder characterization techniques for the optimization of a dry granulation process Authored by: Tim Freeman, Managing Director, Freeman Technology and Hartmut Vom Bey, Vice President, Gerteis Maschinen + Process engineering AG
D
ry granulation is a process applied to convert fine, powders into granular products that flow freely and perform efficiently in subsequent operations. The advantages of roller compaction include modest capital investment, low running and maintenance costs, and high energy efficiency, plus it is particularly suitable for moisture or heat sensitive materials and those that require ultra-high containment. This article presents a collaborative study between Gerteis AG, a market leader in the design and supply of premium roller compaction equipment, and Freeman Technology, specialists in powder characterisation; to identify powder properties that characterise dry granulates to support the optimisation of roller compaction processes.
Controlling dry granulation performance Figure1. Shows a typical Gertiesroller compactor design. Dry powder enters via an inlet funnel, which typically incorporates an agitator to promote consistent flow. Feed and tamp augers control the flow of powder into the compaction zone between two press rollers. An additional hopper can be used for additives or when compacting small volumes. As powder flows between the rollers it is subjected to a controlled force to produce a continuous ribbon of consolidated powder. This ribbon passes into a rotor, breaking it into granules of defined size. Machine selection depends on numerous factors including throughput, and requirements for: • roller heating/cooling • modified roller surfaces • wash-in-place/clean-in-place • regulatory compliance containment
Figure 1: The key features of a roller compactor
The primary parameter for controlling properties of the resulting granules is compaction force which defines the stress that powder is subjected to as it passes through the rollers. The other important parameter is gap width. At any given force, thickness of the ribbon and the rate at which powder is conveyed to the rollers are directly correlated. In some machines, gap width is maintained at a fixed value, so variability in the feed directly impacts the amount of powder in the compaction area and the properties of the ribbon.

Figure 2: Correlating granule properties with compaction force highlights strong relationships with bulk and dynamic properties
This can lead to fluctuations in ribbon and granulate properties. Gerteis machines feature a floating gap design meaning that the distance between the rollers varies to maintain a consistent compaction force and minimise fluctuations in the granules. In summary, properties of the granules are controlled by manipulating the force and gap width.
This raises the question of how to characterise granules to support control of the roller compaction process to produce material that is optimised for manufacturing. A study was undertaken to investigate correlations between dynamic, shear and bulk properties of granules to assess which provides the most valuable data. Investigating the correlation between compaction parameters and granule properties Granules were produced using a model dry granulation blend in a Gerteis MINI-PACTORÂŽ. The resulting granules were characterised using a

FT4 Powder RheometerÂŽ, to measure dynamic, shear and bulk properties [1]. In Phase I, six batches of granules were produced at different compaction forces to investigate the effect of compaction force on granule properties. Roller speed, sieve size and roller gap were kept constant. Table 1 provides full of the experimental conditions. Table 1: Experimental conditions applied to investigate the impact of compaction force. Batches I, III and V were assessed using the full test capabilities of the FT4 Powder Rheometer. However, initial results suggested that shear properties, including wall friction data, showed little correlation with changes in compaction force, suggesting they have limited relevance. Therefore, only dynamic and bulk properties were measured for batches II, IV and VI. Identified.
Tests were conducted in duplicate and the RSD% of the resulting data was typically less than 5%. Figure 1 shows a selection of the strongest correlations Figure 2: Correlating granule properties with compaction force highlights strong relationships with bulk and dynamic properties
As roller compaction force increases, compressibility of the resulting granules decreases, while permeability and conditioned bulk density CBD increase. This suggests that higher compaction forces lead to denser granules that exhibit more efficient particle packing, giving higher bulk density. More efficient packing also reduces the ease with which the volume of powder can be further reduced, i.e. lower compressibility, a change that would influence performance in a tablet press. The permeability profile suggests that higher compaction may influence the level of fines incorporated in the granules.

Cover Story
Fines typically reduce permeability by filling the interstices between larger particles so the observed increase suggests a reduction in fines at higher compaction forces. This would not be counteracted by post-compaction milling which simply reduces the size of overly large granules, rather than controlling particle size distribution. Regarding dynamic properties, the aerated energy (AE) of the granules increases with compaction force. AE is the energy associated with inducing flow when powder is in an aerated or low stress state. Since AE is measured under consistent conditions, the observed increases consistent with increasing particle density. Denser particles are more difficult to aerate so the applied air has less effect on flow energy compared to lighter particles. Basic Flowability Energy (BFE) of the granules increases with compaction force in a similar way to AE, though the relationship is less linear. BFE is the energy associated with forcing a powder to flow and is sensitive to multiple particle properties including stiffness, size and density. Denser particles are more difficult to move under forced conditions so the rise in BFE with compaction force is consistent with the other data. However, the non-linearity of the relationship suggests that changes in size or stiffness may offset this effect at higher compaction pressures.
II, IV and VI were subject to dynamic, bulk and shear characterisation, but shear analysis was omitted for Batches I, III and V, because of its failure to differentiate the samples. To extend the investigation experimental data was also analysed at 9kN/cm compaction force. Table 2: Experimental conditions applied to investigate the impact of roller gap width At both forces, gap width had clear influence on the bulk properties of the granules (see figure 3) with narrower roll gaps producing denser, efficiently packed granules. The permeability profile at 9 kN/cm is more marked than at 4.5kN/cm suggesting that at low gap widths the relatively high compaction force ensures efficient compaction, incorporating the majority of fines into a dense granule. The fact that these data reveal no robust correlations for any other properties measured can be attributed to greater variability in the data.
Phase II of the study investigated correlations between granule properties and gap width. Compaction force was maintained at 4.5 kN/cm, while gap width increased in six discrete steps (see Table 2). Roller speed was kept constant. Batches

Cover Story
Generally, larger roll gaps are associated with less consistent granules as it becomes more difficult to subject the powder to a consistent consolidation regime as roll gap widens.
Conclusion
Direct correlations were observed between the dynamic and bulk properties of granules and the roller compaction force and gap width applied in their manufacture. Increasing compaction force produces denser, more free-flowing granules with lower compressibility and higher permeability. Reducing gap width has a similar, but less pronounced effect. Previous studies [2] have indicated that there is a direct correlation between the dynamic and bulk properties of granules and attributes of tablets produced from them. These results therefore suggest that multi-faceted powder characterisation can provide the data required to optimise roller compaction to ensure high performance of intermediate or finished products.

The FDA approved Retacrit (epoetin alfaepbx) on Tuesday for the treatment of anemia caused by chronic kidney disease, chemotherapy or use of zidovudine in patients with HIV infection. Retacrit is also approved for use before and after surgery to reduce the chance that red blood cell transfusions will be needed because of blood loss during surgery. “While launch timing will ultimately depend on a number of factors, we are moving ahead with the preparation of our launch plans for 2018,” Pfizer said in a statement that seemed to allude to patent litigation it has been fighting with Amgen.
issued a complete response letter and insisted that Pfizer produce more data for its application. The FDA liked the results of that additional effort and a year ago an FDA advisory panel voted 14-1 in favor of recommending approval.
A month later, however, the FDA again sidelined the drug with a second CRL. This time it was because the biosimilar was being manufactured at Pfizer’s Hospira plant in McPhearson, Kansas, that had been issued an FDA warning letter several months earlier. The problems at the plant were laid out in a scathing warning letter that chastised Pfizer for repeated failings throughout the manufacturing network of Hospira, which Pfizer had acquired in 2015 in a $15 billion deal. The drugmaker promised to get on top of the problems and earlier this year, it indicated it had resolved FDA concerns about the facility. While all of this played out, Amgen and J&J continued to reap the benefits of a having an exclusive three years after losing key patents.

Amgen's Aimovig won its first-in-class migraine nod. Will payers step up to the $6,900 price? mgen and Novartis inaugurated a much-anticipated new class of migraine drugs Wednesday with FDA approval for Aimovig, an injectable med laden with blockbuster hopes. But Aimovig has several more hurdles to clear before it can reach those lofty goals.
A
The partners need to win over payers that have already warned how costly this new type of medication—which targets the calcitonin generelated peptide pathway—could be to the healthcare system, and they've started by setting the price at $6,900 per year, lower than the $8,000 to $10,000 payers had warned against.
With a rival drug from Eli Lilly only months behind, Amgen and Novartis have a limited amount of time to make the most of their firstmover advantage. Already, an Express Scripts representative said the company will have a prior authorization program in place to manage access to Aimovig. The approval is arguably more important for Amgen, which is bracing for new biosimilar competition for some key products, including the anemia drug Neupogen. But Novartis has its own financial challenges, including generic competition for its big-selling leukemia drug Gleevec, and with a political scandal raging, it can use this dose of good news.

Business News With Wednesday's nod, the race is on. Amgen had the chance to set initial pricing in the class, VP of Development Rob Lenz said ahead of the approval, and now it can work to capture what he called "pent-up demand" for better migraine meds. "There's a lot of buzz in the field," he said of patient and doctor excitement for the drug. "This is the first preventative therapy ever designed specifically for migraine." As Lenz pointed out, older migraine drugs were repurposed from other uses. That lack of purpose-built treatments is one reason why the cGRP class is so crowded, with other entrants expected from Teva and Allergan as well as Lilly. But Teva's drug, which might have been approved next month, will be delayed by manufacturing problems, that company said in February, giving Amgen and Novartis a little more runway for their launch than previously expected. Allergan's ubrogepant, expected to be the first oral CGRP drug, is farther behind, with a potential FDA filing next year.
Patients will appreciate a tolerability profile that's "similar to a sugar pill" and efficacy that can be seen within days, Lenz said. The once-monthly self-injection allows patients "built-in compliance" because they don't have to remember to take a pill every day, he said. Lilly's injection is also monthly, while Teva's has been tested with monthly and quarterly schedules. Payers could be a tougher crowd, but Amgen may be able to apply some lessons it learned while launching Repatha, a PCSK9 cholesterol drug with blockbuster ambitions. It quickly ran into payer resistance, though, and uptake still isn't as strong as expected.
Sanofi—ran large outcomes trials hoping to show the drugs could deliver cardiovascular benefits. But even with data showing the drugs could reduce CV risks, the PCSK9 drugmakers have discounted their meds by 40% or more to gain coverage. The dynamics have led to sales far below initial projections. Aimovig's approval closely follows a Praluent discount deal Maris sees as a potential harbinger of trouble for the new migraine drugs. For an exclusive spot on the PBM's formulary—and access to millions of patients it covers—Regeneron and Sanofi offered up big price cuts. The deal "does not bode well for the anti-CGRP drug class," Maris wrote this week. At the time of the deal, Bernstein analyst Ronny Gal called it a "capitulation," because of its tacit admission that the class will never become a major commercial success. "When classes go exclusive, payers win," Gal said in a video discussing the deal. Payers have been eyeing CGRP drugs already. In a recent Reuters interview, Express Scripts chief medical officer Steve Miller suggested Amgen avoid the usual approach of setting a high list price and offering large rebates and discounts. The company could trying narrowing the "gross-tonet" gap instead, he suggested. In a statement Thursday, an Express Scripts spokesperson said Amgen is "being responsible" with its Aimovig pricing. While citing "serious unmet need" for migraine sufferers, she said not all patients will need Aimovig. Express Scripts believes the drug is appropriate for patients who have failed on a previous preventative therapy. With that considered, the company will "have a prior authorization program in place to help payers get the most value for the money they spend," she added.

The work is being led by Dr James McCabe, Associate Principal Scientist based at the Macclesfield laboratories of Astra Zeneca.
Pharmaceutical compounds can also be exposed to aqueous environments or moisture during certain processing conditions such as wet granulation during tableting. This means the understanding of critical relative humidities for hydrate formation is of paramount importance. To this end, Dr McCabe is always looking for optimum instrumentation to provide the maximum amount of data. Dr McCabe talks about his experience in using humidity controllers and how he settled on the use of the RH95 system from Linkam. “I have used many humidity systems including dynamic vapour sorption (DVS) from various vendors as well as using them when making environmental X-ray powder diffraction measurements. The advantage of the Linkam RH95 humidity system used in conjunction with one of their temperature stages (THMS600) is that visual changes in crystal/particle morphology (size, shape etc.) can be observed in real time. The stage provides the added ability of then dehydrating samples via elevated temperature as part of the same experiment. This capability is also available on DVS systems, but the images are then macro as opposed to micro. An additional advantage is that in principle a single crystal of material could be assessed using the Linkam humidity system, a sample amount too small for other techniques.” Dr McCabe's work with optical temperature stages has included the use of a new technique called TASC – Thermal Analysis by Structural Characterisation. TASC provides spatially resolved information on thermal transitions to images/movies acquired by temperature stage microscopy. It highlights any structural changes in the sample providing excellent complementary information with traditional forms of differential and modulated differential scanning calorimetry, DSC & MDSC, both being macro techniques.
Dr James McCabe is an Associate Principal Scientist in the Early Product Development Group (EPD) of Astra Zeneca based in Macclesfield in the UK. His research aim is to find the optimal solid form of an active pharmaceutical ingredient (API) for drug development and understand the risks and opportunities associated with that solid form. This includes understanding and mitigating risks associated with hydrate formation as at least 25% of drug molecules can form hydrates.
Dr McCabe is optimistic for future exploitation of TASC in the pharmaceutical industry. “TASC appears to be a powerful thermo-optical technique for measuring optical changes within a sample. Glass transition and melting temperatures can quickly be measured, and complex mixedphase systems can be assessed. I will carry out further work to apply this technique to other areas such as crystal growth (induction times), dissolution and physical stability of amorphous materials when exposed to the combination of both temperature and humidity change.”

Independent White Paper Concludes: Quantum Technology ‘Successfully Addresses many of the Current Limitations seen in Single-Use Pumps’ Rigorous testing and data analysis from independent consultant, PDS Sandbox LLC offers conclusive proof that Watson-Marlow’s Quantum 600 peristaltic pump demonstrates an: “…excellent level of precision across a full range of pressures (up to 4 bar) with low shear that is approximately 50% lower than that of the Quattroflow QF1200SU pump from PSG Dover.”
This pump is ideally suited to filtration and chromatography applications with flows in the range of 3 to 20 liters/minute where high pressure, low pulsation and low shear are required. Based upon the excellent accuracy of the Quantum 600 peristaltic pump, PDS Sandbox also recommends that this technology is used for the delivery of target volumes. In many cases, this removes the need for secondary checks (load cells, scales, flow meters). This provides a simple solution where, after calibration, the pump can be run at a set speed and time to deliver a desired volume accurately enough for a wide range of applications. Commenting on the report, Tony Barrass, Product Manager at Watson-Marlow Fluid Technology says: “We are delighted with the overall conclusions of PDS Sandbox’s report and how well it highlights the superior performance of the Quantum 600 pump in relation to competitor products. The results clearly support our claims that Quantum is both low pulsation and very low shear and also confirms that this innovative new design leads the way in offering linear flow control that is both accurate and independent of downstream pressure. This advances what is possible with peristaltic technology in processes such as tangential flow filtration (TFF), virus filtration (VF) and gradient high precision liquid chromatography (HPLC).”
Published in a White Paper, the results and findings from PDS Sandbox also confirm that the Quantum 600 pump has minimal impact on CHO suspension cell cultures. The report’s opening abstract states: "This performance is better than would be expected with traditional peristaltic pumps and is comparable to the Levitronix PuraLev®200SU centrifugal pump but without the limitations of a strong pressure/flow dependency."
“We have always believed in our exceptional technology. However, to have independent validation reinforces our confidence in Quantum. This is important news for our biotechnology and pharmaceutical customers for whom accuracy across a wide range of pressures and flows and proof of very low shear is essential.” The pump comes with a simple, intuitive control interface and is a robust flexible design with an easy to install single-use pump head cartridge which is reliable and fully validated.

Versatile 96-well MultiTier Microplate System for High Throughput Chromatography The patented 96-well Multi-Tier Microplate System (MTP) from Porvair Sciences and sister company - JG Finneran is a unique device providing analysts with the convenience of an ANSI/SLAS microplate footprint but loaded with inert glass vials.
Minimising the risk of extractables leaching out into samples to be analysed, the MTP accommodates a wide range of vial volumes enabling it to be used for a diverse range of applications. The MTP is formed of sections that can be clipped together to produce a vial holder suitable for 0.5ml, 1ml, 1.5ml or 2ml sample vials. The base plate has a vented bottom to allow uniform transfer of heat or cold to each of the vials and the secure fit of the vials permits use with shakers and vortex mixers during sample preparation. The entire unit can be capped with a pierceable cap mat to prevent contamination and evaporation, consequently the MTP is ideal for use in high throughput chromatography laboratories.
high recovery. Both types of vial can be quickly and easily loaded into the MTP shell using convenient pre-packed Vial Loader packs. Being designed in the industry-standard ANSI/SLAS format, the MTP is compatible with most HPLC autosamplers and many other microplate handling devices, including the Porvair Sciences range of microplate evaporators.

Product Launch “The combination of PQ LC with our PlasmaQuant® MS is a winning formula,” says Ulrich Krauss, CEO of Analytik Jena AG. "By separating various species of an element using HPLC, the mass spectrometer can deliver even more precise results. Not only is this interesting for special analyses, but it makes an entire series of routine analyses more efficient, quicker, and more accurate. And does so without requiring more work by the laboratories.”
High precision is needed primarily in sectors that must be able to detect ever tinier traces of elements in their products and processes. For example, in the food industry the combination of Plasma Quant® MS and PQ LC significantly simplifies the detection of toxic and non-toxic element species. The precision and accuracy of the measurement results also benefit from this. The detection limits here are in the ng/L range.
New sample preparation and concentration platform marks a major advance in automation of GC–MS workflows Markes International (Llantrisant, UK) has announced the launch of Centri®, a fully automated multi-mode sampling and concentration platform for GC–MS.
There are three versions of the PQ LC modules: The space-saving compact PQ LC for routine applications in small lab environments, the standard version of PQ LC for numerous routine and special applications, and the PQ IC ion chromatography system. Individual adaptations to customer requirements and subsequent retrofitting of existing PQ LC modules are also possible. Rounding out the complete solution from Analytik Jena are intuitive controls and analysis software. In addition, a software interface enables the coupling of other HPLC systems to the PlasmaQuant® MS, providing customers with maximum flexibility.

Product Launch Centri uses marketing-leading robotics to reliably automate sampling and preconcentration of volatile and semi-volatile organic compounds (VOCs and SVOCs) through the following sample introduction modes – HiSorb™ high-capacity sorptive extraction, headspace, headspace-trap, SPME, SPME-trap, and thermal desorption.
Analyte flows from all modes can then be concentrated on a sorbent-packed cryogen-free focusing trap, using the same highly successful technology found in Markes’ range of thermal desorption (TD) instruments. It’s this trapping and valve technology, says Markes’ Technical Marketing Director, Dr Massimo Santoro, that underpins several key advantages of the new system: “As well as enabling ppt-level sensitivity and allowing selective purging of interferents such as water and solvents, the trap and valve design used in Centri allows samples to be split and recollected onto a clean sorbent tube – a technology that we pioneered at Markes 20 years ago.”
concentration and GC injection for solids, liquids and vapours. As Santoro says, this allows major productivity improvements to be made: “The use of robotics for all operations makes Centri ideal for many laboratories, especially those who are currently struggling with time-consuming manual sample preparation techniques, such as liquid–liquid extraction and solid-phase extraction. In addition, Centri can desorb industrystandard thermal desorption tubes in compliance with standard methods. These tubes can either be packed with sorbents and used in conjunction with pumped, diffusive or dynamic-headspace sampling, or used to contain small samples of materials and foods, which are then desorbed directly.

“Since then, we’ve found that many analysts value recollection because it allows a single sample to be analysed multiple times. This approach brings numerous benefits to Centri now– for example, reduced need to carry out lengthy sample extraction steps to repeat an analysis, greater peace-of-mind by storage of valuable samples, analysis of a wider concentration range by changing the split flow ratios, and easy validation of complete analyte transfer.” A principal feature of the new platform is that it automates the entire process of sampling, pre-
