• • • •
1100nm within one second Intuitive user interface Small footprint to save valuable lab space Robust design with no moving parts makes for low cost of ownership Open sample area for easy accessory and sample loading
UV/VIS micro-volume spectrophotometers The Excellence UV/VIS microvolume spectrophotometers combine two instruments in one for both microvolume and standard 1cm
Jasco circular dichroism spectrophotometers
T
he J-1000 series circular dichroism spectrophotometers are specifically designed for highsensitivity measurements in the nearand far-UV regions, for scientists that need confidence in the data from characterisation studies of biomolecule structure, function and stability under a wide variety of experimental conditions. Unlike some detectors that only provide good signal-to-noise for low absorbing materials, the J-1000 series
circular dichroism spectrophotometers use high dynamic range detectors to obtain high-quality spectra of samples with excellent signal-to-noise ratio, especially for highly absorbing materials found in the far-UV. The J-1700 was specifically designed for more demanding near-infrared CD applications. Researchers probing the chiral activity of molecules in the NIR spectral region now have the ability to obtain data at wavelengths up to 2 500nm without
Polymer and plastics analysis

etrohm is pleased to present Polymer and plastics analysis a new brochure focusing on quality control in the polymer industry. The brochure includes the latest norms, standards and applications and is available for free from the Metrohm website. Polymers and plastics analysis addresses the analytical challenges along the entire process chain. The brochure provides free access to about 100 applications - most of them are standard-compliant as per ASTM, ISO and DIN EN - to help control the process of polymer production from monomer analysis through to final control of finished products. The new brochure is structured according to the three main steps of the polymer production process: • Quality control of feedstock • Reaction monitoring • Quality control of polymer and plastic products Metrohm offers complete solutions for very specific analytical issues.
Techniques range from titration and ion chromatography to spectroscopy, voltammetry and electrochemistry. The new brochure is a valuable resource to consult for professionals in charge of production and quality control. Critical quality parameters covered are additives, copolymer levels, water content, halogens, residual monomers, heavy metals, impurities, and many more.

cuvette measurements, which are ideal for life science research. • Only requires 1-2µL of your sample • Automatic pathlength selection at 0.1 and 1mm allows for measurements over a large concentration range • No sample dilutions required • Predefined methods for life science applications such as nucleic acid analysis and protein assay
Optimise secure workflows Alongside accuracy and reliability, the range of spectrophotometers and accessories allow one to optimise workflows with full-spectrum scans in just one second and no warm-up time is required. The array technology ensures low maintenance costs. LabX 2019 software creates a secure lab data integrity solution - it allows for complete customisation of UV/VIS workstations to the workflow in the lab and supports compliance with regulations such as 21 CFR Part.

having to manually switch detectors. NIR-CD applications vary from conformational and chirality studies of metal coordination complexes to tuning chiral properties of nanomaterials. Additionally, Magnetic Circular Dichroism (MCD) can be used in conjunction with NIR-CD to probe a chromophore’s electronic structure, as well as to induce chirality in compounds. Furthermore, the flexible design allows field upgrades for different measurement capabilities as applications and budgets evolve.

A unique choice of sampling attachments makes Mira Flex the most versatile handheld Raman system in the market
S
mart Attachments sets the Mira Flex handheld material identification system apart from the competition. We design advanced tips that facilitate acquisitions and track sampling. Diverse attachments for Mira systems enable straightforward sampling of substances of virtually any kind - be they powders, liquids or solids. Smart Attachments is just one step in our quest to provide broad access to advanced chemical analysis for everyone. The next step is Mira Flex, in response to customer requests for even greater flexibility with the Mira system. The new Mira Flex package from Metrohm Raman permits customisation of Mira for unique applications. Mira Flex is an ‘à la carte’ experience: The basic package includes a Mira device, USB cable, Calibration Standard, and laser safety glasses; users can then simply select the available Smart
Attachments and accessories that meet their specific sampling needs. Sampling through a container? The Working Distance Attachments (SWD, LWD, XLWD, or UA) can handle everything from direct contact to 22mm glass containers. Concerned about the toxicity of an unknown? The Standoff Attachment enables safe sampling from a distance. Checking the formulation of a tablet is easy with our Tablet Holder. The Ball Probe Attachment allows sampling by direct contact, e.g. in a barrel with no concern of proper focus. Whether you perform field testing of street drugs or evaluate incoming raw materials - Mira is the fast, easy, reliable and flexible solution for identification and verification of materials.
