Evaluation method of detection result accuracy of rapid organophosphorus and carbamate pesticide residue detector

Abstract

The invention discloses an evaluation method of detection result accuracy of a rapid organophosphorus and carbamate pesticide residue detector. The evaluation method comprises the following steps of: (1) preparing a standard reference sample containing the effective components of organophosphorus and an carbamic acid ester; (2) determining an enzyme inhibition ratio reference value and standard deviation of the standard reference sample; (3) measuring the enzyme inhibition ratio of the standard reference sample by using the rapid organophosphorus and carbamate pesticide residue detector; (4) comparing an enzyme inhibition ratio detection value and the enzyme inhibition ratio reference value; and (5) obtaining an evaluation result. The evaluation method provided by the invention can effectively evaluate the detection result accuracy of the rapid organophosphorus and carbamate pesticide residue detector.

Description

technical field [0001] The invention relates to the field of detection of organophosphorus and carbamate pesticide residues, in particular to an evaluation method for the accuracy of detection results of a rapid detector for organophosphorus and carbamate pesticide residues. Background technique [0002] As food safety is getting more and more attention, the state and social organizations have invested a lot of money to purchase various rapid detection equipment, and organophosphorus and carbamate pesticide residues are the most common pesticide residue detection items, but currently various rapid detection instruments There are many manufacturers of reagents and reagents. At present, there is no national or industry unified standard for the rapid detector of organophosphorus and carbamate pesticide residues. There is a lack of a method that can accurately evaluate the accuracy of the detection results of the rapid detector. The risk of accuracy has been out of control for a...

[0002] As food safety is getting more and more attention, the state and social organizations have invested a lot of money to purchase various rapid detection equipment, and organophosphorus and carbamate pesticide residues are the most common pesticide residue detection items, but currently various rapid detection instruments There are many manufacturers of reagents and reagents. At present, there is no national or industry unified standard for the rapid detector of organophosphorus and carbamate pesticide residues. There is a lack of a method that can accurately evaluate the accuracy of the detection results of the rapid detector. The risk of accuracy has been out of control for a long time, resulting in the phenomenon that the same sample often has completely different test results from different testing institutions
