QuEChERS is a pretreatment method for agricultural products proposed by the U.S. Department of agriculture in 2003. At present, QuEChERS has been widely used in the detection of food, environmental water samples and soil pollutants, especially in the analysis of pesticide residues in fruits and vegetables, veterinary drugs and additives.
Provide flexible QuEChERS package, including different specifications of centrifuge tubes, extraction tubes, purification tubes and reagent bags, to help you quickly establish a standard testing scheme.
Product advantages
