Analyzer Liquid Shut-Off
Our new Analyzer Liquid Shutoff (ALS) prevents liquid of any kind from entering your gas chromatograph, keeping the analyzer columns safe from damage and saving you expensive repairs or column replacement. The ALS installs quickly and easily to both field and laboratory gas chromatographs and features a see-through sight window for instant visual confirmation of flow status. The ALS is equipped with a shut-off ball that floats on the free liquid and moves up to shut off the flow of liquid slugs that will flood the analyzer. The ALS should be used on chromatography, portable and permanently mounted, calorimeters, moisture analyzers and stack sampling systems. The ALS is another Welker Patented Product designed to improve your company's profitability.

Welker Liquid Eliminator Membrane Filter
The Welker Liquid Eliminator (LE-2) is designed to protect analyzers from damage and contamination by removing liquids and particulates in gas samples. The gas sample enters the housing and flows through the membrane, effectively eliminating any free liquids from entering the analyzer columns. The LE-2 is mounted horizontally, allowing the liquid droplets or slugs to drop off of the membrane and drain out through the bottom valve. The replaceable membrane is supported by a stainless steel retaining screen that allows the filter to be back purged without damage to the membrane. The Welker Liquid Eliminator is available in Delrin (w.p. 300psi), Aluminum (w.p. 1 000psi) and Stainless Steel (w.p.1440psi) allowing you to choose the model that is correct for your pressure needs.
