[Case Study] Analysis of Residual Pesticides in Food Using High-Resolution GCMS
Reliable simultaneous analysis of 325 pesticide components in food matrices unaffected by interference using high-resolution GC-MS.
In the quantitative analysis of pesticide residues in food, triple quadrupole mass spectrometers such as GC-MS/MS and LC-MS/MS are commonly used. This is because they can separate trace amounts of pesticides from the food matrix and detect peaks with high sensitivity. On the other hand, our Orbitrap mass spectrometer allows for advanced mass separation, enabling the detection of pesticide peaks without interference from the food-derived matrix. This application note introduces a simultaneous analysis of 325 pesticide components using a GC-Orbitrap mass spectrometer. The Orbitrap mass spectrometer facilitates method development for data acquisition in Full MS measurements, and its high mass accuracy allows for the precise estimation of molecular formulas for each fragment ion, providing reliable quantitative information.
