McHale Measurement has in-house, mobile (domestic and international) and on-site Natural Gas Chromatography capabilities. We offer natural gas analysis and report to ASTM D1945 standards.

McHale Measurement performs calibration checks at the beginning AND end of each analysis day, ensuring that there was no drift outside of the accepted tolerances. Standard in-house lead time is five (5) to six (6) business days and expedited services are available.


ASTM D1945 – 14
Standard Test Method for Analysis of Natural Gas by Gas Chromatography

Significance and Use

The ASTM Standard Test Method provides data for calculating physical properties of the sample, such as heating value and relative density, or for monitoring the concentrations of one or more of the components in a mixture.

The method covers the determination of the chemical composition of natural gases and similar gaseous mixtures within the range of composition. It may be abbreviated for the analysis of lean natural gases containing negligible amounts of hexanes and higher hydrocarbons, or for the determination of one or more components, as required.

The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
