ABSTRACT

The analysis of semi-volatile organics in wastewater requires the use of single quadrupole mass spectrometry operated in full scan mode. A pesticide analysis requires gas chromatography with electron capture detection. These two separate methods require separate extractions and two different instruments. Commercially available triple quadrupole GCMS instruments are capable of operating in full scan mode. These instruments, when operated in MRM mode, are also capable of meeting and/or exceeding the detection limit requirements for pesticides. This presentation describes measuring semi-volatiles and pesticides in one extract, on the same triple quadrupole instrument, with two injections: one injection for semi-volatiles and one injection for pesticides.
