Date: 2017-04-06

QuEChERS(Quick、Easy、Cheap、Effective、Rugged、Safe) is the latest in the world to develop a new product for the detection of agricultural products, rapid sample pretreatment technology, by the US Department of Agriculture Professor Anastassiades developed in 2003.



 

Principle:

The principle is similar to high performance liquid chromatography (HPLC) and solid phase extraction (SPE),are the use of adsorbent filler and matrix impurities in the interaction, adsorption impurities to achieve the purpose of purification purification.

Advantage:

(1)high recovery rate:For a large number of polar and volatile pesticide varieties of the recovery rate of more than 85%.
(2)Accuracy and accuracy.
(3)Can be analyzed for a wide range of pesticides, including polar, non-polar pesticide species, can use this technology to get a better recovery rate.
(4)Easy to operate:without good training and high skills can be well completed.
