- Established an effective, fast, simple sample preparation method of plant-derived food.
- Realized simultaneous quantitative analysis of multi pesticides and metabolites, such as organophosphates, organochlorines, pyrethroids, triazoles, amides, triazines and carbamate esters.
- SHIMSEN QuEChERS provides centrifuge tubes containing prefilled amounts of salts and SPF sorbents, used in formalized EN and AOAC method, to improve laboratory efficiency and throughput.
Introduction
Fruits and vegetables are people daily food. In order to ensure yield and quality, pesticides are usually used in the planting process of fruits and vegetables. Therefore, pesticide residues in fruits and vegetables have always been a food safety issue of concern to people, and detection criteria for pesticide residues has been established to protect food safety.
In QuEChERS method, the use of loose extraction salts and cleanup SPF sorbents in combination with shaking and centrifugation steps result in a Quick, Easy, Cheap, Effective, Rugged and Safe sample preparation technique[1]. QuEChERS has been used in analysis of multi pesticides, PAH, PCB, PBDE and flame retardants, etc., and been formalized in worldwide.
In this method, we realized a simultaneous quantitative analysis of multi pesticides in plant-derived food, that is pear, leek, tea and rice, using Shimadzu GGMS-TQ8050. The samples were pretreated by SHIMSEN QuEChERS extraction salts and dispersive SPF sorbents and separated by SH-1701 GC column.
