Fast Multi-Residue Pesticide Analysis in Soil and Vegetable Samples

The strict detection limits that are required for the quantitation of pesticide residues in food and environmental samples requires the use of very sensitive, selective, and rugged LC/MS/MS technologies. In this application note the benefits of using LC/MS/MS for this type of analysis...

Simultaneous Determination of Residues of Approximately 100 Pesticides and Metabolites in Fruit and Vegetables by LC/MS/MS

Many pesticides, which are difficult or generally not to analyse by GC/MS, can be identified and quantified by LC/MS/MS. After simple solvent extraction and fast cleanup the extracts are analysed using matrix-matched standards. The drawback of MS/MS methods is laborious parameter optimization for each target analyte. This effort can...
