Pesticide Residue - an overview ScienceDirect Topics

Pesticide residues in foods are basically determined using GC. Although this technique shows some limitations for some pesticides, such as N- methylcarbamates, most of them are either retained on the chromatographic column or decomposed to their corresponding phenols.

Pesticide Residue - an overview ScienceDirect Topics

GC, HPLC, MS, and immunoassay (ELISA) are usually used in determining pesticide residues. A reliable and highly sensitive determination of multipesticide residues can be achieved by chromatography techniques coupled with MS, tandem MS (MS/MS), triple quadrupole MS, or high-resolution MS (Q-TOF).
