ASTM D8098-23
(Test Method)Standard Test Method for Permanent Gases in C2 and C3 Hydrocarbon Products by Gas Chromatography and Pulse Discharge Helium Ionization Detector
Standard Test Method for Permanent Gases in C<inf>2</inf> and C<inf>3</inf> Hydrocarbon Products by Gas Chromatography and Pulse Discharge Helium Ionization Detector
SIGNIFICANCE AND USE
5.1 The presence of trace amounts of hydrogen, oxygen, carbon monoxide, and carbon dioxide can have deleterious effects in certain processes using hydrocarbon products as feed stock. This test method is suitable for setting specifications, for use as an internal quality control tool, and for use in development and research work.
SCOPE
1.1 This test method covers the determination of hydrogen, nitrogen, oxygen, methane, carbon monoxide, and carbon dioxide in the parts per billion mole (nmol/mol) to parts per million mole (µmol/mol) range in C2 and C3 hydrocarbons.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For some specific hazard statements, see Annex A1.
1.3.1 The user is advised to obtain LPG safety training for the safe operation of this test method procedure and related activities.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Summary of Test Method
4.1 The sample is separated in a gas chromatographic system using gas chromatography columns. Hydrogen, oxygen, nitrogen,
methane, carbon monoxide, and carbon dioxide (also known as the permanent gases) are detected on a pulse discharge detector.
The concentration of the gases to be determined is calculated from the peak areas relative to an external standard. Helium is the
required carrier gas for this detector. Ultra-high purity carrier gases and leak-free gas chromatography (GC) systems with getters
are essential due to the extreme sensitivity of the detector. Argon, if present in the sample, may interfere with oxygen
determination.
