Efficient Analysis of Residual Pesticides in Foods Using High-Sensitivity GC-MS/MS

Introduction

In the analysis of residual pesticides in foods, periodic maintenance is required. This includes the replacement of insert liners and column cutting due to the impact of impurities originating in the foods. However, because of issues such as the time for maintenance procedures and the cost of consumables, there is a need to reduce the frequency of maintenance as much as possible. The GCMS-TQ8050, a high-sensitivity GC-MS/MS, can detect trace ions with high sensitivity, so high quantitative accuracy is obtained even for trace components. Using the high-sensitivity TQ8050, existing lower limits of quantitation can be obtained with small injection volumes. Further, reducing the injection volume lessens the analysis burden on parts such as insert liners, columns, and the ion source, which, in turn, reduces the frequency of maintenance. This Application Data Sheet presents the analysis results of pesticide standard samples and actual tomato samples, under conditions in which the injection volume is reduced to 1/4 the conventional amount, using the GCMS-TQ8050.
