ASTM WK29560

    New Test Method for Permanent Gases in C2 and C3 Products by Capillary Gas Chromatography and Pulse Discharge Helium Ionization Detector

    (What is a Work Item?)

    Developed by Subcommittee: D02.D0.02 | Committee D02 | Contact Staff Manager


    1. Scope

    This test method covers the determination of hydrogen, nitrogen, oxygen, carbon monoxide and carbon dioxide in the parts per million volume (ppmv) to parts per billion (ppbv) range in C2 and C3 products. This method uses capillary chromatography and Pulse Discharge Helium Ionization Detector for separation and detection.

    The specification requirements for these perminate gases requires lower detection limits that this method addresses with recent technology improvements.
