QuEChERS means "Quick, Easy, Cheap, Effective, Rugged and Safe", which was first introduced by USDA and scientists in 2003. The procedure of QuEChERS extraction simplified the cleanup for pesticide residues analysis. It uses minimal
amount of solvent along with extraction salts to extract the analytes into organic phase for cleanup then followed by dispersive solid phase extraction. Due to the high flexibility of the procedure, sample after treated can be directly introduced to determinative device such as LC-MS/MS or GC/MS. It has become increasingly popular in the area of multi-residue pesticide analysis in food and agricultural products.
MAS-Q (Multi-mechanism Adsorption SPE-QuEChERS) is an application of modified QuEChERS method which is suitable for most of the pesticides residue analysis, drug or antibiotic residue analysis in vegetable, fruit, grain, and animal
▲ Single extraction method could be applied to different kinds of sample matrix;
▲ High recovery rate for multiple pesticides residue analysis;
▲ Universal Clean-up kits are optimized for different application requirement;
▲ The method is simple, fast, reproducible and labor-saving.
● The clean up kits are available in 2 mL, 15 mL for different sample volume
requirement, and extraction kits are packed in anhydrous sealed packets;
● Superior centrifuge tubes and glass homogeneous ball provide you a simple and
Slim bag package
Recommended Standard Operating Procedure for MAS-Q
● Step 1: Extraction
Weight comminuted sample (10 g or 15 g) into a 50mL centrifuge tube, and then open the extraction kit package, add the salt after adding your solvent to the sample. Extraction into the organic layer. Four glass homogeneous balls are suggested to add in to break the MgSO4 caking caused by sample rich in water.
● Step 2: Cleanup
Take proper supernatant from step one, and add it into a selected clean up tube which is suited to the food matrix also the method you are following. 2 mL or 15 mL centrifuge tube containing different kind of SPE sorbent and MgSO4 is
available for different sample volume. The sorbent will adsorb the interfering matrix, and the MgSO4 helps remove excess water.
