Trace & Purity Oxygen Analyzers

Industrial Gas can be separated into bulk gas, speciality gas and ultra-high purity (UHP) gases. Within the PST 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). Even if the gas purity is certified, the transport system from the cylinder to the point of use must be of the highest integrity as there is approximately 210,000 ppm O2 in the atmosphere, so point of use analyzers are recommended. For membrane or (V)PSA separators our Mogas, GPR-3100 or XTP501 analyzers can measure the purity of the oxygen produced.
