ASTM WK43353

    Revision of D7833 - 12 Standard Test Method for Determination of Hydrocarbons and Non-Hydrocarbon Gases in Gaseous Mixtures by Gas Chromatography

    (What is a Work Item?)

    Active Standard: D7833 - 14

    Developed by Subcommittee: D03.07 | Committee D03 | Contact Staff Manager


    1. Rationale

    Numerous editorial and minor technical errors require correction: 9.3.3: isobutene is the same as isobutylene. It should read isobutane. 12.1: Calculations are used for all components, not specific for hydrocarbons only. Equation 5 was written incorrectly. The operator should be multiply, not divide. Table 1: The table displays all components, not only hydrocarbons Figure 1: One peak is incorrectly labeled argon/nitrogen. The correct label is argon/oxygen. Appendix X1: The Fahrenheit equivalent of 10C/min is 18F/min, not 50F/min. Makeup gas flow, column flow rates, and column linear velocity do not apply to thermal conductivity detectors and packed columns. This information should be removed.
