Pesticide residue detection liquid preparation method and control system

Abstract

The invention relates to a pesticide residue detection liquid preparation method and a control system. The detection method comprises the following steps: adding a sample into the liquid mixing tube according to the required amount, adding the extracting agent with the required amount into the mixing tube filled with the sample, extracting the residual pesticide in the sample, carrying out oscillation mixing in a mechanical reciprocating motion mode in the extraction process, filtering the extract liquor after the extraction is completed, and putting the filtered extract liquor into the cuvette; a colorimetric method is adopted for residual pesticide detection, detection data are obtained, a filter layer is arranged at the bottom of the liquid mixing pipe, and the filter layer in the liquid mixing pipe is used for filtering extract liquor. The detection system comprises a multi-tube mixing device and a colorimetric detection device, and detection can be implemented by adopting the method. The method can be used for agricultural product pesticide residue detection and other similar occasions, is convenient for agricultural product pesticide residue detection, and is beneficial for realizing the consistency of extraction effects and the comparability of detection results.
