QuEChERS

Advantages of the QuEChERS procedure

The QuEChERS procedure entails a number of simple analytical steps and is thus fast and easy to perform and little susceptible to errors. QuEChERS provides high recoveries for a very broad scope of pesticides belonging to various chemical classes and the final extract, being solved in acetonitrile, gives full flexibility in the choice of the determinative analysis technique. Direct connection with liquid chromatography (LC) and gas chromatography (GC) is possible.
