ABSTRACT:
A system and process for determining the concentration of nonmethane organic chemicals in a gaseous sample includes a separation system to receive the gaseous sample. In the separation system nonmethane organic chemicals including ethylene and ethane are reversibly retained on a packing material while methane and inert gases pass through the separation system and are vented. Thereafter a carrier gas is directed through the separation system, the nonmethane organic chemicals are released into the carrier gas, and the carrier gas containing the organic chemicals is conveyed to an analyzer for analysis of the organic chemicals.
