QUICK EXTRACTION KIT FOR AGRICULTURAL PRODUCT PESTICIDE RESIDUE DETECTION PROCEDURE AND METHOD FOR OBTAINING STOCK SOLUTION OF DETECTION SOLUTION FROM AGRICULTURAL PRODUCT SAMPLE
QUICK EXTRACTION KIT FOR AGRICULTURAL PRODUCT PESTICIDE RESIDUE DETECTION PROCEDURE AND METHOD FOR OBTAINING STOCK SOLUTION OF DETECTION SOLUTION FROM AGRICULTURAL PRODUCT SAMPLE
A quick extraction kit for an agricultural product pesticide residue detection procedure and method for obtaining a stock solution of a detection solution from an agricultural product sample; the quick extraction kit comprises a tubular column, a first mixed powder layer and a second mixed powder layer; and the first mixed powder layer can adsorb moisture of a sample solution to buffer the pH value of the sample solution, and the second mixed powder layer can absorb remaining moisture and an impurity in the sample solution. The method comprises: acquiring a crushed powder of the agricultural product sample; adding an extraction solution to the crushed powder of the agricultural product sample to obtain the sample solution; adding the sample solution to the tubular column of the quick extraction kit; and driving the sample solution in the tubular column to flow through the tubular column and to be discharged out of the tubular column to obtain the stock solution of the detection solution. The quick extraction kit and method of use thereof solve the problem in the prior art that a pesticide residue detection result cannot be quickly obtained.
