Textiles - Determination of phosphate compounds

WARNING - Persons using this document shall be familiar with normal laboratory practice. This document does not purport to address all of the safety problems. 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.
