Scope
Scope: This document specifies the purge-trap/gas chromatography-mass spectrometry method for the determination of methyl tert-butyl ether in soil. This document is applicable to the determination of methyl tert-butyl ether in soil. When the sample amount is 5 g and a full scan analysis is performed using a standard quadrupole mass spectrometer, the method detection limit for the target substance is 0.2 μg/kg, and the determination limit is 0.8 μg/kg; Main technical content: Methyl tert-butyl ether in soil samples is purged and enriched in the trap tube by high-purity helium (or nitrogen), the trap tube is heated and backflushed with high-purity helium, and the components desorbed by heat enter the gas chromatograph for separation and detection using a mass spectrometer. The target substance is identified by comparing with the standard mass spectrum and retention time, and quantified using the internal standard method.
