Product Description

The QuEChERS method is a streamlined approach that makes it easier and less expensive for analytical chemists to examine pesticide residues in food. The name is a portmanteau word formed from "Quick, Easy, Cheap, Effective, Rugged, and Safe"

1.The extracted aliquot of sample will be added to a 2 ml or 15 ml centrifuge tube containing a certain amount of SPE dispersive sorbent and MgSO4.The sorbent will pull out interfering matrix materials from the sample, while MgSO4 helps to remove excess water and improve analyte partitioning.
2.You can choose suitable QuEChERS Dispersive SPE tube according to the volume of  sample aliquot and sample contents
3.Customized also accepted
