QuEChERS extraction salts contain pre-weighed anhydrous extractable salts, in which anhydrous magnesium sulfate is used to remove water from the sample matrix, and other buffer salts are used to provide a suitable pH to ensure a good recovery rate for some alkali-sensitive pesticides.
When a sample with relatively large water content is encountered, an exothermic reaction occurs between QuEChERS extraction salts and water, thus affecting the recovery rate. When used, the buffer salt can be added after adding the organic solvent to prevent local overheating of the sample.
Features of QuEChERS Extraction Salts
1. Effectively improve the human efficiency of the laboratory and all components are pre-accurate weighing.
2. Ensure the repeatability of the analysis results. Full automatic production, eliminate manual packaging error.
3. Ensure the recovery rate and sensitivity of the multi-residue analysis. QuEChERS extraction salts are specially optimized with no interference of impurities.
4. Convenient transportation and storage, which can greatly reduce the use cost.

Package of QuEChERS Extraction Salts
Pure grade, magnesium sulfate for water removal is packaged after drying in a high-temperature oven to avoid losing its original function due to damp.
