Full title and description
ASTM D2504-88(2015) — Standard Test Method for Noncondensable Gases in C2 and Lighter Hydrocarbon Products by Gas Chromatography. This short method specifies the procedure for determining trace amounts (parts per million by volume) of noncondensable gases—principally hydrogen, nitrogen, oxygen, and carbon monoxide—in ethane, propane, methane and other C2 and lighter hydrocarbon products using gas chromatography techniques.
Abstract
This standard describes a gas-chromatographic test method for the measurement and reporting of selected noncondensable gases in light hydrocarbon streams (C2 and lighter). It is intended for use in specification-setting, routine quality control, and research where detection of hydrogen, nitrogen, oxygen, and carbon monoxide at ppmv levels is required. The method emphasizes proper sampling, calibration, chromatographic separation and reporting in SI units.

Scope
This test method covers the determination of hydrogen, nitrogen, oxygen, and carbon monoxide in the parts-per-million by volume (ppmv) range in C2 and lighter hydrocarbon products. It is intended to be applicable to light hydrocarbons (other than ethylene in some cases where not validated) and specifies reporting in SI units; it also notes that users are responsible for safety practices and regulatory compliance when applying the method.
Key topics and requirements
- Detection and quantification of noncondensable gases (H2, N2, O2, CO) in C2 and lighter hydrocarbon streams at ppmv levels.
- Use of gas chromatography with appropriate columns, detectors and calibration gases to achieve required sensitivity and selectivity.
- Sampling and sample-handling procedures to avoid adsorption or contamination of trace gases.
- Calibration, limits of detection/quantitation, and reporting conventions — results reported in SI units (ppmv) with stated precision and accuracy considerations.
- Applicability notes and safety/responsibility statements for users, with references to an informative annex for specific hazard statements.
Typical use and users
Used by refinery and petrochemical laboratory analysts, quality control departments, process chemists, and research groups monitoring feedstock purity or product quality where low-level noncondensable gases can affect downstream processing or catalyst performance. Also used by specifications writers and vendors specifying acceptance criteria for light hydrocarbon products.
Related standards
Related ASTM test methods and Committee D02 documents governing petroleum product analysis and gas-chromatographic techniques are commonly used alongside D2504. Laboratories often refer to other ASTM GC methods for hydrocarbon and permanent gas analyses and to Committee D02 publications for sampling and precision statements. (Users should consult the current Committee D02 index for the most relevant companion standards.)
