Trace Oxygen Analyzers

Industrial Gas can be separated into bulk gas, speciality gas and ultra-high purity (UHP) gases. Within the Avcray Group we have a range of analyzers to measure oxygen as well as other impurities. Our Pico-Ion sensors from AII provide dependable, repeatable oxygen measurements in semiconductor grade UHP gases such as nitrogen (N2), Argon (Ar), helium (He) and hydrogen (H2), with a minimum output range of 0 to 50 ppb O2 (parts per billion) with a lowest detection limit of < 100 ppt O2 (parts per trillion).
