ASTM D4526: Standard Practice for Determination of Volatiles in Polymers by Static Headspace Gas Chromatography
SDO: ASTM: ASTM International
DOD Adopted ANSI Approved Approved
Headspace gas chromatography (GC) involves the determination of volatile components in a polymer solution by gas chromatography of a vapor phase in thermal equilibrium with the sample matrix. Volatiles in finely ground insoluble polymers can also be determined with and without an extracting solvent.
This practice provides two procedures:
Procedure A-Automatic headspace analysis.
Procedure B-Manual injection headspace analysis.
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. Specific precautionary statements are given in Section 6.
