Method for the determination of 326 Residual Pesticides in Rice using LCMS-8045 and GCMS-TQ8040 NX

User Benefits

・A modified QuEChERS extraction procedure has been employed for quantifying the pesticides at the desirable concentration levels by using Ultra-fast technologies of LCMSTM-8045 and GCMS-TQTM8040 NX. ・Shorter run time of analysis increases the productivity and throughput of the LC-MS/MS and GC-MS/MS system. ・Method employs lower injection volume and lesser flow rate, enhancing column life and stability of assay over longer durations of analysis.

Introduction

Rice is the most widely consumed staple food for a large part of the world's human population, especially in Asia. It is the agricultural commodity with the third-highest worldwide production. To meet the continuous demand of consumption and to increase the yield rate, several pesticides and chemicals are used during the entire life cycle of rice crop. Therefore, Maximum Residual Limits (MRL) are listed by various international regulatory bodies for wide variety of pesticides. Thus, increasing the importance of analytical method for determination of a range of pesticides present in rice. Based on these requirements, Shimadzu Application Development Center (ADC) has developed and validated a simple, sensitive and high throughput multiclass, multiresidue method for the determination of 326 pesticides in rice by using LCMS-8045 and GCMS-TQ8040 NX. The multi-residue extraction was performed with modified QuEChERS method for simultaneous quantification of 220 pesticides by LC-MS/MS and 158 pesticides by GC-MS/MS. Out of these, 52 pesticides were common and analyzed by both the techniques.
