ASTM WK45819

    Revision of D4815 - 13 Standard Test Method for Determination of MTBE, ETBE, TAME, DIPE, tertiary-Amyl Alcohol and C1 to C4 Alcohols in Gasoline by Gas Chromatography

    (What is a Work Item?)

    Active Standard: D4815 - 15a

    Developed by Subcommittee: D02.04.0L | Committee D02 | Contact Staff Manager


    1. Rationale

    To be added as an Appendix for information purposes: Helium is a widely used carrier gas for most capillary gas chromatographic applications. Recent disruptions in helium supplies combined with higher prices have prompted the search for alternative carrier gases where heliums chromatographic properties are not critical to the methods performance. Nitrogen is a suitable helium replacement and is much easier to obtain at lower cost. This appendix contains instrument conditions and results obtained using nitrogen carrier gas for the analysis of ethanol and MtBE in pump gasoline samples.
