Small portable pumping station, consisting of roughing pump, air cooled diffusion pump, and liquid nitrogen cold trap, permits onsite sampling followed by quantitative laboratory analysis of residual gases.
Sampling process was developed which uses commercially available high pressure filters and provides measurements in fraction of time required by older methods. Measurements show no significant difference in results between low pressure and high pressure samples. Filter method is slightly more accurate than scrubber technique.
Special analytical column having in series two separate absorption sections charged with beads of porous polymer and a sample of gas detects traces of hydrocarbons. New method requires only 15 minutes for execution.
