适用范围

1.1 This test method describes a liquid chromatograph procedure for the separation of some additives currently used in low density polyethylene. These additives are extracted with 2-propanol prior to liquid chromatographic separation. The ultraviolet absorbance (200 nm) of the compound(s) is measured; quantitation is performed using the internal standard method.

1.2 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. For a specific hazards statement, see Section 9.
