Simultaneous Determination of Pesticide Residues in Vegetable Extract by LC/MS/MS [LCMS™-8050]

Introduction

To protect food safety, it is important to establish detection criteria for pesticide residues and methods to improve accuracy when measuring the concentration of the target substances. Generally, the standard addition method and matrix-matched calibration curve are more useful techniques for reducing the matrix effect than the absolute calibration method. However, these techniques are not necessarily simple, since an independent calibration curve is required for each sample of a wide variety of samples. In this report, we introduce an LC/MS/MS analysis technique which is capable of obtaining high recovery accuracy with the absolute calibration method.
