QuEChERS dispersion solid-phase extraction:

　　QuEChERS is a sample pretreatment method proposed by Anastassiades in 2003, which has been widely used in the detection of food, environmental water samples, and soil pollutants. The QuEChERS kit includes centrifuge tubes, extraction tubes, purification tubes, and reagent bags of different specifications to help you quickly establish standardized testing methods.

characteristic:

● Good recovery rate for most pesticides

● Less operation steps, reducing human error

● Safer for operators and more environmentally friendly

● Simple, fast, and cost-effective

Related standards:

QuEChERS products are applicable to NY/T of the Chinese Ministry of Agriculture, AOAC of the United States, and EN related methods of the European Union.
