Screening analysis of Dechlorane Plus and UV-328 by PY-GC/MS method
1. Introduction
Dechlorane Plus (DP) is widely used to Electronics and Textile products as Chlorinated flame retardants and UV-328 is widely used to Paint and Plastic products as UV absorber. However, these two compounds became regulation target of Persistent Organic Pollutants treaty (POPs) in 2023 due to concerns that their flame resistance, high concentration and long-term toxicity will have a bad influence on the human body. As a screening analysis for judgment of containing/not containing on the same kind regulation target, there is an analysis method of phthalate esters by PY-GC/MS in the IEC62321-8. This method allows direct analysis without sample pretreatment. This study tried to analyze of DP and UV-328 by PY (PY-3030D, FRONTIER LAB)-GC/MS method using the JMS-Q1600GC UltraQuad™ SQ-Zeta. As the result, good reproducibility and detection sensitivity were obtained and It seemed to quite possible to screening analysis.
