Abstract: The pesticide residue limits in food are strictly regulated by each region or country in order to protect the people’s health. In recent years, the number of pesticides regulated around the world is on the rise.
The QuEChERS method published by the USDA (United States Department of Agriculture) in 2003, which has been adopted as an official method by organizations such as the Association of Analytical Communities (AOAC) and Committee of European Normalization (CEN), enables efficient extraction of pesticides without the need for special equipment. However, there are problems with reproducibility being dependent on operators and the time required for the work.
In this article, an example of comprehensive analysis of residual pesticides in spinach using a Revive In-Line Sample Preparation (ILSP) column1) (RESTEK Co.) and the quadrupole time-of-flight mass spectrometer LCMS-9050 (Fig. 1) is introduced. The Revive ILSP column, which enables on-line cleanup of compounds derived from the matrix, makes the sample preparation quicker and easier. It is also expected that this method can contribute to the reduction of waste and costs associated with pretreatment.
