1.1 This test method covers the determination of residue in LPG by automated thermal desorption/gas chromatography (ATD/GC) using flame ionization detection (FID).

1.2 The quantitation of residue covers a component boiling point range from 69°C to 522°C, equivalent to the boiling points of C 6 through C 40 n-paraffins.

1.2.1 The boiling range covers possible LPG contaminants such as gasoline, diesel fuel, phthalates and compressor oil. Qualitative information on the nature of the residue can be obtained from this test method.

1.2.2 Materials insoluble in LPG and components which do not elute from the gas chromatograph or which have no response in a flame ionization detector are not determined.

1.2.3 The reporting limit (or limit of quantitation) for total residue is 6.7 µg/g.

1.2.4 The dynamic range of residue quantitation is 6.7 to 3300 µg/g.

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

1.4  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 and health practices and determine the applicability of regulatory limitations prior to use.
