The H2 Quality Analyzer measures impurities in Hydrogen. The H2 Quality Analyzer can use either a HE12 detector of FID detector to measure trace amount of O2+Ar, N2, Kr, CH4, CO, CO2 and THC in Hydrogen streams. Depending on the impurities that you are looking to measure the HE12, FID, or both can be implemented into the system to produce the best results and solutions as required by the end user.
