Method Validation and Measurement Uncertainty Estimation for Determination of Multiclass Pesticide Residues in Tomato by Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS)

<div>Mass spectra of carbaryl showing collision-induced dissociation of precursor [M + H]<sup>+</sup> ion (m/z 202.1) into m/z 145.0 and m/z 127.0 (a) and the ion ratios of transition from 202.1 to 145.0 and 202.1 to 127.0 (b). The ion ratio for two transitions in carbaryl was found to be between 29.8 and 44.5, indicated by the two dotted lines, and this was also used to identify carbaryl in a sample accurately. Similarly, the more intense transition, 202.1 to 145.0, was used as the quantifier ion for carbaryl.</div>
