Analysis of Pesticides Residues in Brown Rice by LCMS-8050RX

User Benefits

－Enables quick and simple sample preparation by combining the QuEChERS extraction process with an on-line purification column. －LCMS-8050RXenables analysis with good recovery rates and reproducibility.

Introduction

With the increase in the number of regulated pesticides, more effective methods for simultaneous analysis of residual pesticides in food are required. The QuEChERS method, which is widely used for pesticide residue analysis, is a pretreatment method that consists of an extraction step with acetonitrile and salts or a buffer and a purification step with dispersive solid-phase extraction (dSPE). The method can efficiently extract and purify pesticides without special equipment, but there are problems with operator-dependent data variability and the long time required for the process. Revive in-line sample preparation (ILSP) columns1) (RESTEK Co.) are pretreatment columns that can be incorporated into the LC flow path for on-line cleanup of matrix-derived components. It makes the sample preparation process quicker and simpler, and it can be expected to reduce plastic consumable waste and costs associated with pretreatment. This article describes the results of comparing the purification efficiency of a Revive ILSP column versus a dSPE using an LCMS-8050RX.
