Textiles - Determination of benzene residues
WARNING —— Persons using this document shall be familiar with normal laboratory practice. This document does not purport to address all of the safety problems, if any, associated with its use. 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 a method for determining residual benzene in textile products using headspace gas chromatography-mass spectrometer (HS-GC-MS).
This document is applicable to various textiles.
2 Normative references
N/A.
3 Terms and definitions
No terms and definitions are listed in this document.
4 Principle
Put the specimen in a sealed container. Benzene in the specimen volatilizes into the container after equilibrium at the specified temperature and time. Extract the air in the head space of the container and inject it into gas chromatography-mass spectrometer for determination. Quantify it by internal standard curve method.
