ASTM D1945 – Natural Gas
Air Technology has extensive experience in the analysis of natural gas or refinery gas. Samples are collected in stainless steel canisters, which are then analyzed by GC/FID/TCD. The analysis determines the concentration of several hydrocarbon species from which it can then calculate a BTU and specific gravity.
