Inlet Solvent Filters General Use Inlet Solvent Filters Large surface areas prevent pump cavitation Disposable 2 µm, 10 µm, and 20 µm pore sizes available General use and prep filters for higher flow applications

Application Note Why Use An Inlet Solvent Filter?

It is good practice to filter your solvents to prevent pump damage.

Upchurch Scientific® 316 stainless steel filters provide that protection.

To filter out particulate matter from the solvent that may otherwise damage expensive hardware. (Use a 10 µm or 20 µm version for this purpose. The A-309 and A-230A filters have an added “Bottom of the Bottle™” feature to help draw solvent to within 1/8” of the bottom of your solvent bottle.)

Because filters should be changed periodically, we make it easy to replace them without tools. For those filters using a plastic fitting, the tubing can be reconnected by finger tightening the fitting into the new filter. The filters with stems allow easy insertion into the inlet tubing.

To prevent particulates originating from the sparging system from entering the mobile phase reservoir and to help disperse the sparging gas efficiently. (Use a 2 µm filter for this purpose.)

To hold your tubing in place at the bottom of the bottle. (Most stainless steel filter options work best for this purpose.)

Important Note: It is usually a good idea to change the inlet filter as part of your semi-annual or annual preventative maintenance program.

Precolumn and Inline Filters Very High Pressure Filters Inline and precolumn configurations available Pressure rated to 15,000 psi (1,035 bar) Low internal volume

The two new VHP Filters are available for UHPLC applications, where filtering particulates from the system is extremely important to prolonging the life of sub-2 µm particle columns. Place the Inline VHP Filter between the pump and injection valve to prolong the life of the injection valve rotor seal by removing any particulates generated by wear of the pump seal. The small volume of the Inline Filter minimizes the introduction of dispersion in the system. Select from 0.2 or 0.5 µm porosity rating for both filter styles.

The unique Precolumn VHP Filter offers additional column protection designed to connect directly into the 10-32 coned port of your column or other piece of hardware. Incorporating a spring loaded, self-adjusting tube, the Precolumn Filter adjusts to any port depth, eliminating any possibility of dead volume. The Precolumn Filter can be reused in multiple ports and a good connection is ensured every time. The replacement product for the Precolumn Filter is easy to use and includes a fresh piece of stainless steel tubing, which extends the lifetime of the assembly.

Connect 1/16” OD and 10-32 coned fittings from pages 17, 19 and 20. The VHP Inline and Precolumn Filters include five replaceable frit assemblies, which can also be purchased separately in packs of ten.

ColumnSaver™ Precolumn Filter Economical protection for your analytical column Finger tight to 6,000 psi (414 bar) without wrenches or other tools Lower dead volume than conventional filters with holders Universal connection compatible with all column manufacturers’ fittings Compatibility with stainless steel or PEEK™ tubing

The PEEK ColumnSaver Precolumn Filters offer all the protection of conventional precolumn filters at a third of the cost. With its convenient direct connect design, changeover time is measured in seconds and no tools or wrenches are needed. The ColumnSaver PEEK body contains a HiFlo™ stainless steel or titanium filter element and is designed for maximum filtration of particulate matter with minimal dead volume or backpressure.

The stainless steel ColumnSaver Precolumn Filter offers similar benefits as the PEEK version, but it is especially designed for use in UHPLC applications. Manufactured with an all-stainless steel body and featuring a 2 µm stainless steel frit, the stainless steel ColumnSaver offers precolumn filtration protection in those applications where inline pressures can reach as high as 20,000 psi (1,379 bar). (Please Note: Because of the design of this product, it needs to be wrenchtightened in place.)

0.5 µm or 2 µm porosity frits available Great column protection Feature stainless steel bodies and polymer-encased stainless steel frits

Upchurch Scientific® Standard Precolumn Filters have 0.020” (0.50 mm) diameter thru-holes and 8° distribution cones for minimal band spreading and mixing. They feature stainless steel bodies, and pressure rated to 6,000 psi (414 bar) and both accept 1/16” OD tubing and standard 10-32 threaded high pressure fittings.

Excellent for general purpose inline use 2 µm and 20 µm porosity frits available

Placed between the pump and sample injection valve, Inline Solvent Filters trap particles released through normal piston seal wear. Without an inline filter, particles can be flushed through your system’s tubing to the sample injection valve, resulting in valve damage and further system contamination.

With a 0.010” (0.25 mm) diameter thru-hole, our A-318 Filter has one of the lowest swept volumes (0.61 µL*) of any analytical HPLC precolumn filter available, ensuring maximum protection with very little band broadening. Pressure rated to 6,000 psi (414 bar).

These filters are pressure rated to 6,000 psi (414 bar) and use a 2 µm or 20 µm stainless steel frit. An 8° distribution cone helps spread the flow of the mobile phase over the entire surface of the frit, while the 0.050” (1.3 mm) diameter thru-hole allows virtually unrestricted solvent flow rates.

Application Note

Note

Increase the Life of Your Column

What’s the Difference Between Precolumn & Inline Filters?

Why use a Precolumn Filter when there is a frit at the head of the column itself? Changing the column frit is extremely difficult to do without disturbing the column packing. A precolumn filter provides relatively inexpensive insurance against column damage, and changing its frit is easy. A Precolumn Filter placed between the sample injection valve and the HPLC column protects the column from particles originating in the sample and from pump and valve seal wear.

You may have noticed that the bodies of Precolumn and Inline Filters look similar, and as such, you may have wondered what the differences are.

Because Precolumn Filters, by definition, are typically placed in a volumesensitive area immediately preceding the column, these filters usually feature smaller thru-holes, smaller frit diameters, and lower overall internal volumes.

In contrast, Inline Filters are often placed where the internal volume is not as critical and where longer life and less fluid restriction is more important.

Biocompatible Semi-Prep Inline Filters

Designed for high flow applications

The A-330 High Pressure Semi-Prep Filter has a swept volume of 223 µL and has been tested with water at flow rates up to 100 mL/min. At this rate the filter adds only 50 psi (3 bar) additional back pressure.

1.14” (2.90 cm)

1.05” (2.67 cm)

0.050” (0.13 cm) thru-hole

Versions for 1/16”, 1/8”, 3/16”, 1/4” and 5/16” OD tubing 100% PEEK™ flow path

Biocompatible Semi-Prep Filters consist of a stainless steel body, two PEEK end fittings, and a separate PEEK frit. The A-410 and A-411 are pressure rated to 6,000 psi (414 bar), while the A-510 and A-511 are for lower pressure applications and have threaded ports designed to connect large bore tubing. These filters are ideal for many higher flow analytical, semi-prep and preparative applications. Best of all, if the filter becomes clogged, simply unscrew the assembly, remove the frit and replace it.

As an added benefit and for greater flexibility, the frits used with each of these assemblies are interchangeable.

Upchurch Scientific® Inline MicroFilters protect your column from particles originating in the mobile phase or sample, or from pump seal and sample injection valve wear. These filters have a 0.006” (150 µm) thru-hole. Choose the M-520 with a 0.5 µm 100% PEEK frit or the M-135 1 µm stainless steel filtering screen version, to connect to capillary tubing using the MicroTight tubing sleeves (page 19).

You may also directly connect 1/32” OD tubing using the M-525 which contains a 0.5 µm PEEK frit.

The Precolumn MicroFilters directly connect into your microbore or analytical column. Total theoretical void volume is only 0.5 µL (includes frit volume) and the PEEK tubing used in the assembly of these units has a 0.005” (125 µm) ID, virtually eliminating any mixing of the sample with the mobile phase.

Application Note The Mini MicroFilter (page 165) and Inline MicroFilter can be used to pack capillary tubing. Simply place one of these filters on the effluent side of the capillary tubing, then slurry pack. Once packed, place a filter at the head of the tubing. This creates a reliable capillary column without fusing the silica to make frits or pressing filter paper inside the capillary tubing.

Patented Upchurch Scientific® PEEK Frits offer exceptionally uniform porosity. This property ensures longer filtration life and consistent frit-to-frit swept volumes. The PEEK polymer frit discs are biocompatible and inert to most solvents, making them well-suited for bioanalytical applications. PEEK’s robust properties make these products suitable for low and high pressure applications.

Disc rings, included on most PEEK frits, are made of PCTFE and are slightly thicker than the frit disc, providing enhanced sealing and excellent chemical resistance. PCTFE surrounded PEEK frits can be used up to 80 ºC, and PEEK frits alone are a good choice for applications up to 100 ºC.

Frit Volume

0.125” (0.32 cm) diameter 0.062” (0.16 cm) thick

The term “frit volume” refers to the volume of the various fluid pathways that comprise the matrix of a frit. A standard frit is a mass of small particles fused together through a controlled process of compression and heat.

Because of their shape, there are gaps between the fused particles. Fluid makes its way through these gaps, creating a pathway from one side of the frit to the other. (See the diagram, below, where the white circles represent frit particles, and the black area represents the void between the particles.)

0.125” (0.32 cm) diameter 0.062” (0.16 cm) thick

Generally, when the frit particles increase in size, the frit’s porosity increases as well. The larger the particles, the larger the gaps between particles.

Cumulatively, these gaps comprise what is known as “frit volume”. Using gravimetric determination, it has been experimentally shown that the total volume of any given frit may range from 18%–30%, depending upon the porosity of the frit.

Frit volume is calculated by determining what the mass of the frit would be if it were a solid block of material of equal size. Then the solid mass of the frit is multiplied by the percentage assigned to the porosity to determine the theoretical frit volume.

18% for 0.2 µm frits 20% for 0.5 µm frits 24% for 2 µm frits 26% for 5 µm frits 28% for 10 µm frits 30% for 20 µm frits From a chromatographic perspective, it’s important to know the volume of the frit used in your system. It is possible for a frit to negatively impact your chromatography if the total frit volume is too large and if it is placed in an area through which the sample will pass. To avoid frit-related problems like band broadening and loss of resolution, most inline filters placed after the sample introduction point (e.g., between the injection valve and the column) are smaller in size and porosity than inline filters that are placed in areas before the sample is introduced into the flow path (e.g., between the pump and the injection valve).

Note

Titanium is a biocompatible alternative to stainless steel. Our 0.2 µm, 0.5 µm and 2 µm porosity titanium frits are surrounded by PEEK or PCTFE polymer rings for enhanced sealing. The dimensions of most of these frits make them suitable replacement frits for Upchurch Scientific® filters and guard columns.

Frits

Stainless Steel Frits Upchurch Scientific® 316 Analytical-scale Stainless Steel Frits are available in 0.5 µm or 2 µm porosity—the most common HPLC filtration ratings. Each frit includes a PCTFE or PEEK™ polymer sealing ring.

Many of the frits shown have the common 0.250” (0.64 cm) and 0.254” (0.64 cm) ODs, which allow them to be used in the precolumn and inline filters found starting on page 160. Choose the larger diameter faces and/or larger porosity frits for faster flow rates. Choose frits with a smaller diameter face and/or smaller porosity for applications sensitive to extra flow path volume.

It is rarely worth the time and effort to clean frits, given the relatively low cost of replacements. Furthermore, cleaning may leave some debris embedded in the frit pores. If the washed frit is accidently returned to your instrument in a reverse orientation, any remaining debris could be flushed out and deposited further down the fluid path. If this frit is being used as a column head frit, the debris may be washed directly onto the column bed.

Filters & Frits

Bottle Caps and Plugs

Bottle Caps Extremely simple — no threaded ports or fittings Manufactured from ETFE and Polypropylene

If you are looking for a bottle cap that is quick and easy to use, but still allows many connection options, we have just what you need!

The Bottle Caps fit standard GL-45 (1 L) or smaller-neck GL-38 (4 L) glass bottles.

Each cap has three holes. With two of the holes you simply push your tubing straight through. The third hole, with a luer taper, can be used for a number of options. Any male luer (such as a luer-lock syringe) will fit snugly in this hole, or you can use the A-626 or A-627 Plug. Exceptions are the A-610 and A-610B Bottle Caps. Please see the note below right.

Application Note A self-regulating sparging system can help reduce helium consumption and improve pump performance. Set this up by pressing your tubing through the appropriate holes in your bottle cap and attaching each line to a filter. Sparge your mobile phase with an inert gas (preferably helium) for 15–20 minutes. Then reduce the outlet pressure of the sparging gas to a maximum of 5 psi (0.34 bar) and insert a plug (A-626 or A-628) into the remaining port of the cap. The sparging gas will shut off once the incoming pressure equals the pressure inside the reservoir. As the mobile phase is consumed and the internal pressure lowers, sparging gas will enter to keep the system pressurized and degassed. Please Note: If gas leaks while pressurizing the bottle, try removing the sealing ring from the bottle, as it sometimes interferes with the sealing of Upchurch Scientific bottle caps.

One concern with sparging systems is the possibility of solvent backing up the sparging inlet line. This can occur if the gas tank completely evacuates with the regulating valves open, creating a vacuum in the tubing. Solvent backup may damage sparging system components and cause crosscontamination of mobile phase reservoirs. To help prevent solvent backup, install the CV-3010 Inline Check Valve (page 151) along the tubing line that runs between the gas supply and the solvent bottle.

Bottle Cap Plugs and Adapters Use the A-626 Bottle Cap Plug to seal the third “tapered” luer hole found in most Upchurch Scientific® Bottle Caps. Or, use the A-628 Plug to seal any unused 1/16” or 1/8” bottle cap holes.

Alternatively, try the A-627 or A-629 Filter Bottle Cap Plug to cap an unused hole in your bottle cap. The 20 µm stainless steel frit in these products prevents foreign matter from contaminating your solvent while leaving the bottle open to the atmosphere, thus allowing fluid to be pulled out without creating a vacuum (generally not used with sparging applications). All plug bodies are manufactured from ultrahigh molecular weight polyethylene (UHMWPE).

Our P-600 Bottle Cap Adapter is designed to allow the use of 1/32” OD tubing with our caps. Just insert the Adapter into a tubing cap hole, then connect your 1/32” OD tubing with our F-126S or F-126H MicroTight® Fitting (page 18).

For a more efficient degassing system, please see the Systec® HPLC Vacuum Degassing Systems on pages 177 – 178.

Please see the Quick-Stop Luer Check Valve on page 151 for another solvent inlet Application Note.

Note The A-610 and A-610B Bottle Caps have a slightly different configuration than the other caps. One hole accepts 3/16” OD tubing, the typical size used with a Waters® system. The remaining two holes accept 1/8” OD tubing. Unlike the other caps, the A-610 does not have a tapered luer hole. If desired, use our A-628 Plug or A-629 Filter Plug for one of the 1/8” holes.
