Analysis of Dechlorane Plus Residues in Environmental Water Using GCMS-TQ8050 NX with Boosted Efficiency Ion Source (BEIS) and Long-Life Filament

User Benefits

- The combination of the BEIS and long-life filament enables high sensitivity analysis while maintaining long-term stability. - The ¹³C-Dechlorane 602 is used as internal standard (IS) in the optimization method to avoid the interference of isotope IS with target components in MRM mode.

Introduction

Dechlorane Plus (DP) is a synthetic substance mainly used as an adhesive, sealant and flame retardant for polymers in the industrial field. Due to its strong persistence and bioaccumulation, there is a significant risk to human and environmental health. In 2018, the European Chemicals Agency (ECHA) identified it as a Substance of Very High Concern (SVHC), and in June 2021 proposed to add it to Appendix XVII of the REACH regulation to restrict it, proposing to ban the production and use of DPs and prohibit the production and launch on the market of goods with DP content equal to or greater than 0.1% (by weight). In May 2023, the Stockholm Convention on Persistent Organic Pollutants (POPs) listed DP in Appendix A. At the same time, DP is also included in China's List of new pollutants under Key Control (2023 version). A method for the determination of residues of DPs in environmental water was established by using the Shimadzu GCMS-TQ8050 NX equipped with Boost Efficiency Ion Source and long-life filament. This application news provides an important analytical method for determine the residue levels of new pollutants in environment with high sensitivity and good stability.
