Embodiment Construction

[0025] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] figure 1 It is a structural block diagram of the whole machine of the automatic fruit and vegetable pesticide residue detector of the present invention. It can be seen from the figure that the upper sampling needle movement assembly 1 includes the sampling needle and the movement assembly that the sampling needle moves along the X, Y and Z directions, wherein the X and Y directions are sliding components, and the Z direction is a belt drive. Assemblies, the sampling needle movement assembly 1 is integrally slid and fixed on the support 9. The base 5 is fixed with the sample pretreatment module 2 and the pesticide residue detection module 3 , and the reagent rack 6 and the PC host 8 are on the right side. The front side of the sample pretreatment module 2 is the pesticide residue detection module 3, the right side is the reagent rack 6...

Abstract

Provided is a detection method for the pesticide residue detector. The method comprises the following steps: step A, selecting a sample; step B, initial test condition detection: detecting whether the current state of the pesticide residue detector meets the test requirement of the current sample period or not; step C, starting the current sample period test; step D, determining a detection result; in the step D, a historical contrast value which is the same as or close to the detection condition of the current sample period test is searched in a contrast value database to serve as a current contrast value for determining a detection result. After the detection method is adopted, historical contrast data can be fully utilized, automatic pesticide residue detection of fruit and vegetable samples can be rapidly and efficiently completed in a standardized mode, meanwhile, the problem that detection operation of detection personnel is not standard is avoided, the accuracy of the detection data is improved, the workload of the detection personnel is reduced, and the working efficiency is improved; the method is especially used in food safety rapid detection.

Description

technical field [0001] The invention relates to a detection method for a pesticide residue detector and a corresponding pesticide residue detector, which are mainly used in the field of rapid detection of food safety. Background technique [0002] The principle of spectrophotometric detection of pesticide residues: Under certain conditions, organophosphorus and carbamate pesticides can inhibit the normal function of cholinesterase, and the inhibition rate is positively correlated with the concentration of pesticides. Under normal circumstances, the enzyme catalyzes the hydrolysis of the neurotransmitter metabolite (acetylcholine), and the hydrolyzed product reacts with the chromogenic agent to produce a yellow substance. The change of absorbance with time at 412nm is measured with a spectrophotometer, and the inhibition rate is calculated. By inhibiting The rate can determine whether there is a high dose of organophosphorus or carbamate pesticides in the sample. [0003] Ho...
