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 chromatographs, portable and permanently mounted, calorimeters, moisture analyzers and stack sampling systems. The ALS is another designed to improve your company’s profitability.
