Agilent Low Part-per-Billion Level Pesticides Screening in Traditional Chinese Medicine Using the Agilent 7000A GC/MS/MS

Update: 30 September, 2023

This paper describes the use of gas chromatography coupled with triple quadrupole mass spectrometry (GC/MS/MS) to screen pesticides in Traditional Chinese Medicine (TCM) at levels as low as 1 ppb. The Triple Quadrupole mass spec- trometer, when used in Multiple Reaction Monitoring (MRM) mode, can dramatical- ly remove matrix interferences and significantly increase the effective signal-to- noise ratio (S/N).
