Carrier gas purity is essential in any application requiring extreme sensitivity. Impurities limit detector sensitivity and can even destroy capillary columns. The Valco helium purifier (HP2) provides "point-of-use" gas purification of helium or other noble gases, such as Ar, Ne, Kr, and Xe, to sub-ppm levels of reactive gaseous impurities. The nitrogen purifier (NP2) does the same for nitrogen.

The gas purification substrate in Valco gas purifiers is a non-evaporable heat-activated gettering alloy. This stable alloy is contained in a welded assembly, so the purifiers can be used safely in industrial applications with minimal precautions. The helium and nitrogen purifiers feature a self-regulating design which maintains the getter material at the optimum temperature and eliminates the possibility of thermal runaway.

Available for 110 VAC or 230 VAC.
