Standard Practice for Determination of Volatiles in Polymers by Static Headspace Gas Chromatography
 N D4526

Annotation

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.

NOTE 1-There is no known ISO equivalent to this standard.

Общепринятая практика для определения летучих веществ в полимерах статической газовой хроматографией Headspace

Газовая хроматография (GC) Headspace включает определение летучих компонентов в растворе полимера газовой хроматографией паровой фазы в тепловом равновесии с типовой матрицей. Летучие вещества в нерастворимых полимерах мелкого помола могут также быть определены с и без растворителя извлечения.
