| And also, to develop a multi-residue LC/MS/MS screening method to detect 35 pesticides, and to exhibit the absence of “cross-talk” between co-eluting components.
An H-SRM LC/MS/MS method to monitor 35 pesticide residues was developed using the TSQ Quantum Discovery. All 35 pesticide residues were quantitated in 18 minutes. Using H-SRM, interferences from the sample matrix background were substantially reduced, leading to improved LOQs. Similarly, no cross-talk issues were detected for any of the tested analytes.
Compared with traditional single pesticide analysis methods, the sample preparation procedures are usually simplified in multi-pesticide analysis methods. This means more interference from the sample matrix may be present making H-SRM the technique of choice for improving detection limits.
