UHP O2 Program

These test programs are designed to analyze ultra high purity (UHP) commodity or rare gases according to CGA or customer supplied specifications (ex. 99.9 – 99.9999% [3 “nines” to 6 “nines” purity]). Sampling is done either directly from a customer supplied  DOT cylinder or by renting small, high purity sampling cylinders and specialized transfill hardware accessories (ex. low-dead volume pressure regulators, transfer lines [plus special transfill instructions]) from ALI.
