It is the responsibility of the user to establish appropriate safety and health practices and to ensure compliance with any national regulatory conditions.
1 Scope
This document describes the gas chromatography and gas chromatography-mass spectrometry (GC-MS) methods for the determination of the content of eight phosphate compounds in textiles.
This document is applicable to all kinds of textiles.
2 Normative references
No normative reference is listed in this document.
3 Terms and definitions
No terms and definitions are listed in this document.
4 Principle
The specimens are extracted ultrasonically with ethyl acetate, and after being filtered by membrane, the extract solutions will be determined by a gas chromatograph equipped with a flame photometric detector (P-type), or determined by gas chromatograph-mass spectrometer and quantified by external standard method.
