T/HTES 008-2022 Determination of Polybrominated Biphenyl Ethers and Methoxylated Polybrominated Biphenyl Ethers by Gas Chromatography-Mass Spectrometry (GC-MS) for Textiles
Basic Information
Scope
Scope: This document provides a method for determining the content of 10 polybrominated diphenyl ethers (including monobrominated to decabrominated congeners) and 8 methoxy polybrominated diphenyl ethers (including monobrominated to octabrominated congeners) in textiles using a gas chromatography-mass spectrometry (GC-MS) instrument. This document is applicable to the determination of the content of polybrominated diphenyl ethers and methoxy polybrominated diphenyl ethers in various textile products; Main technical content: The polybrominated diphenyl ethers and methoxy polybrominated diphenyl ethers in textiles are extracted by pressurized fluid extraction or ultrasonic extraction. The extract is concentrated and then injected into a gas chromatography-mass spectrometry instrument for detection. The quantification is performed using the isotope internal standard method.
