Let’s take a good look at the Quick, Easy, Cheap, Effective, Rugged, and Safe sample preparation technique: QuEChERS, the most efficient solid-phase extraction method for detecting pesticide residues in food. And Hawach QuEChERS products can make procedures easier than ever.
Packed with 50ml empty tube, Hawach QuEChERS extraction salts offer you a pre-weighed anhydrous extract salt. The anhydrous magnesium sulfate is to remove water from the sample matrix, and other buffer salts can provide a suitable pH to make sure that some alkali-sensitive pesticides have a good recovery rate.
When the sample comes with relatively high water content, the recovery rate might be influenced by the QuEChERS buffer salt reacting exothermically with water. Now you don’t need to worry about it because Hawach has separate extraction salt packs available, and you can add buffer salts after adding organic solvents.
You don’t need the specialized glassware when you use QuEChERS extraction salts as well. Free-flowing extraction salts and salt packets can perfectly fit into the extraction tubes and make transferring the salts to your sample neat and easy.
Food safety problem
Environmental pollution caused by unreasonable use of pesticides has caused widespread concern. So does food safety. With the enhancement of environmental awareness and the rapid development of the economy, the governments of various countries have paid more and more attention to the monitoring of pesticide residues in the environment and food. Strengthening research on pesticide residue detection technology has important theoretical and practical significance for the rational use of pesticides, environmental protection, and human health protection.
