1. Scope |
1.1 This test method establishes standard conditions for the separation and identification of methyl esters by gas-liquid chromatography. 1.2 This test method is applicable to animal and vegetable fatty acids and oils having 8 to 24 carbon atoms. The use of the polyester liquid phase facilitates the separation of both the saturated and various unsaturated fatty acid methyl esters on the chromatogram obtained. 1.3 The conditions specified in this test method are not suitable for determining epoxy and oxidized fatty acids nor to fatty acids that have been polymerized. See also Test Methods D2800 and D3457. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 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. |
