Embodiment 1

[0058] Such as figure 1 As shown, the sample to be tested is poured into the container 110, shaken sufficiently to make it evenly mixed to form an aqueous solution. Start the electrochemical detector 120 and drop the aqueous solution into the reaction area 126 of the electrode test piece 120 . The electrochemical detector 120 will automatically apply a suitable voltage and measure the current caused by the reaction at the same time. The microprocessor 122 calculates the content of the pesticide in the sample to be tested, and the result is presented on the display 123 in a quantitative manner. The used electrode test strips 121 are discarded.

Embodiment 2

[0060] Such as image 3 As shown, the sample to be tested is poured into the container 110, and the drug powder (containing a single analysis dose of AChE and buffer salt B) placed in the capsule is added, and shaken sufficiently to make it evenly mixed to form an aqueous solution. Start the electrochemical detector 120 and drop the aqueous solution into the reaction area 126 of the electrode test piece 121 . The electrochemical detector 120 will automatically measure the current induced by the reaction and input it to the microprocessor 122 . The microprocessor 122 calculates the difference between the actual reaction temperature and the ideal temperature according to the temperature compensation module 300 , and calculates the error caused by the difference accordingly, and then presents the result on the display 123 with graphics or lights. The used electrode test strips 121 are discarded.

Abstract

The invention discloses an analyzing device and method of enzyme inhibitor in the solution, which consists of electrode test piece and electrochemical detector, wherein the electrode test piece only provides one-time analysis for user. The invention can also be used to test the pesticide residues in the vegetable and fruit.

Description

technical field [0001] The invention relates to an analysis device and method of enzyme inhibitors, in particular to the detection of enzyme inhibitor pesticides by means of electrochemical analysis. Background technique [0002] There are many methods known to analyze pesticide residues in fruits and vegetables, such as spectrophotometry, atomic absorption spectrometry, thin-layer chromatography, gas chromatography, liquid chromatography, nuclear magnetic resonance spectroscopy, fluorescence methods, etc., among which Gas chromatography and liquid chromatography are more commonly used because of their good reproducibility, sensitivity, and the advantages of being able to determine the types of pesticides. However, these methods require professional and technical personnel to prepare a large number of test solutions in the laboratory, and cannot be easily analyzed by untrained personnel in general consumer purchasing places such as crop production areas, markets, and superma...
