Detection and Quantitation of Brominated and Chlorinated Hydrocarbons by DART with Linear Ion Trap and Triple Quadrupole Technology

摘要

1. The linear ion trap MS with the DART-SVP in 1D transmission mode provided an excellent method of detecting BFRs and OCs, providing precursor and fragment ion information. 2. The Quantum Access MAX MS with the DART-SVP in direct infusion mode generated full scan spectra for BFRs and OCs that 1) generated a high quality match to theoretical spectra confirming the precursor information provided by the linear ion trap and 2) facilitated the automated optimization of tube lens voltages, transition fragments, and collision energies. 3. BFR and OC quantitative experiments were performed and LODs were found to be as low as 50 ppb for several compounds. 4. Further work to minimize sample response variation and investigate the effect of matrix on sample response will be performed. 5. DART-SVP provides a quick simple method of analyzing BFRs and OCs without the need for sample preparation or chromatographic method development.
