Problems solved by technology

However, the conventional heating device has the disadvantages that the sample liquid is easy to leak, the card is not easily fixed and incomplete contact with the gasket, and the heating takes a long time to cause the sample liquid to evaporate, so the test results cannot be accurately presented.
In addition, this method takes a long time to operate, and the operator has the risk of direct contact with the extraction solution containing pesticides and other pollution.

Embodiment

[0069] Figure 5 Flowchart of the analytical method using the enzyme inhibitor of the present invention. Firstly, in step S500, the test strip of the present invention is provided. As mentioned above, this test includes the corresponding enzyme gasket and color reagent gasket, and then, in step S510, the detection test piece is placed in the fixture for fixing and supporting, and the unknown insecticide is passed through step S520 The content sample solution or the solution to be tested of the blank test sample is dropped on the enzyme gasket. In step S530, the clamp is folded by using the connecting piece, and then the color-developing agent gasket and the enzyme gasket are folded and closely contacted in step S540. Reaction, which can be based on the content of the enzyme inhibitor in the sample liquid, then in step S550, the fixture is placed in the detection device, and measured by the detection device, step S560, measure the difference in reflected light value with an in...

Abstract

The invention relates to a detection device and a method of quantitative analysis of enzyme inhibitors, the detection device comprises a memory unit which is used for storing at least one group of detection parameters; an interface which is used for containing a test strip to be measured; a reflective optical detection unit which provides a light beam to the test strip to be measured and generates a measurement signal; a microprocessor which is based on the detection parameters to process the measurement signal, so as to obtain a quantitative detection result; and a display unit which is used for outputting the detection result.

Description

technical field [0001] The present invention relates to a detection device and method, in particular, to a detection device and method for quantitative analysis of enzyme inhibitors by reflection optical analysis. Background technique [0002] Conventional methods for analyzing pesticide (enzyme inhibitor) residues in fruits and vegetables include spectrophotometry, atomic absorption spectrometry, capillary gas chromatography, gas chromatography, liquid chromatography, fluorescence, immunoassay... .wait. At present, gas chromatography and liquid chromatography are generally used, because of their good reproducibility, sensitivity, and the ability to determine the types of pesticides. However, each of the aforementioned methods requires professional technicians to prepare a large number of test solutions in the laboratory, which cannot be easily carried out in the field or in the places where general consumers come and go, so that the analysis work can be carried out in any ...
