High purity gas analysis gas chromatographG51-GH

High purity gas analysis gas chromatographsummary:

G51 is an economical high-purity gas analyzer suitable for impurity analysis in gases such as hydrogen, oxygen, argon, nitrogen, helium, neon, krypton, xenon, methane, carbon dioxide, etc; Detect the minimum concentrations of H2, O2, and N2 above 1:1ppm, and CO, CH4, and CO2 above 2.01ppm, meeting the requirements for high-purity gas analysis with purity ranging from 99.99% to 99.999%.

If ppb ppt level impurities need to be detected, helium ionization detectors PHHID and plasma discharge detectors EPD with central cutting systems can be selected, with a minimum concentration of up to 100ppm for detection
