Scope
This standard specifies the gas chromatography-mass spectrometry (GC-MS) analysis method for seven main components of liquefied petroleum gas, including propane, propylene, butane, 1-butene, isobutane, isobutylene, and cis-butene. It also prescribes the GC-MS analysis method for major components of natural gas, such as methane.
This standard is applicable to the qualitative analysis of the main components of liquefied petroleum gas and natural gas in biological samples (blood, liver, brain, lungs, etc.).
