This miniature gettering helium purifier (HPM) is designed to be installed in a gas chromatograph's flow path to purify a single stream. A smaller version of VICI’s standard-size HP2 purifier, the HPM will remove any contaminants introduced by flow controllers, elastomeric tube seals, pressure regulators, crude traps, or other system components that are not completely clean and leak-tight. It 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.
Carrier gas purity is essential in any extremely sensitive application. Impurities limit detector sensitivity and can even destroy capillary columns. Based on 10 ppm total inlet impurities, outlet impurities are less than 10 ppb for H2O, H2, O2, N2, NO, NH3, CO, CO2, and CH4. Other impurities removed include CF4, CCl4, SiH4, and light hydrocarbons.
Note: These gettering helium purifiers are unsurpassed at removing nitrogen. For applications that can tolerate slightly more nitrogen, unheated VICI Metronics helium purifiers offer an economical option.
