Quantitative analysis of airborne semi-volatile flame retardants using sorbent tube sampling with TD–GC–MS

contributed by Markes International Ltd | 09/24/2018

This study introduces the results of research into the performance of sorbent-tube sampling and Markes’ thermal desorption (TD) systems for the analysis of two classes of flame retardants of current concern – polybrominated diphenyl ethers (PBDEs) and organophosphates (OPs). Key indicators of method performance for these challenging semi-volatile compounds are reproducibilities <10.3%, carryovers <3.2%, linearities >0.998 and LODs <0.171 ng/m³, with a field study demonstrating the detection of OPs in indoor air at low ng/m³ levels.
