  1. The AFS Non-Hazardous Option - A Game Changer!

    The AFS Non-Hazardous Option - A Game Changer!

    The AFS has long been one of our flag ship gas purifier products here at CRS. It has remarkable lifetimes that wipe out the competition, with the combined benefit of the site glass for moisture and oxygen indicators. The only potential downfall that we repeatedly run into with end users was its “hazardous” shipping status. The media used in the AFS that allows for these extremely long lifetimes is also its downfall for end users that aren’t set up for receiving these special items, or want to deal with the extra cost associated with a hazardous shipping program.

  3. 3A Moisture Trap for SFC

    3A Moisture Trap for SFC

    Chromatography Research Supplies (CRS) has developed a moisture filter specifically targeted to SFC end-users in petrochemical analysis using carbon dioxide as their mobile phase. In this specific application, the adsorption properties of the typical 5A or 13X molecular sieve media can cause rapid heating of the purifier cylinders from CO2 adsorption as well as the intended H2O molecules. With the CRS 3A molecular sieve filter, the smaller pore size allows for the removal of moisture while excluding almost all larger molecules, including the CO2 being used as the carrier.

    New! Purifier Recommendation and Lifetime Estimate Inquiry Form
