Pesticide detection device

Abstract

Provided is a pesticide detection device including a housing body, a light source module, a focal scanning system, a miniature spectrograph, and a control switch. The light source module is arranged in the housing body to project white light beam, a UVA light beam, or a UVB light beam. The focal scanning system is arranged in the housing body to focus the light beam projected by the light source module and to enable the light beam to scan an object to be detected. The miniature spectrograph is used for receiving the light beam projected by the object to be detected and analyses the pesticide residual quantity based on the light beam. The control switch is arranged at the housing body and is electrically connected with the focal scanning system. The light source module is controlled by the control switch to project the white light beam, the UVA light beam and the UVB light beam to the object to be detected, so that the pesticide residual quantity on the object to be detected can be analyzed out. The pesticide detection device provided not only can rapidly detect out the pesticide residual quantity, but also can greatly increase the accuracy of the pesticide residual quantity.

Description

technical field [0001] The invention relates to a pesticide detection device, in particular to a pesticide detection device which utilizes ultraviolet light and white light to achieve detection and correction. Background technique [0002] In today's society, due to the rise of consumer awareness, food safety and hygiene, especially the problem of pesticide residues in vegetables and fruits has become the focus of attention. As for the personal safety anxiety caused by it, it has prompted countries all over the world to have stricter requirements on the safety inspection of agricultural products, and the exporting countries of agricultural products will be more important in the quality control of exported agricultural products. The market for pesticide residue inspection of agricultural products has huge potential, and it is estimated that the market size can reach billions of dollars in output value. [0003] Traditional chemical pesticides can be divided into nine categor...

Problems solved by technology

Among them, the enzyme inhibition method (China Taiwan Patent No. I325497 and M376764) utilizes organophosphorus and carbamates to inhibit cholinesterases, and the inhibition rate is positively correlated with its concentration, which can be used to determine whether there are pesticide residues , but this method needs to be kept at a constant temperature of 37 degrees Celsius in the general analysis process, and the preservation of the enzyme is a major problem; China Taiwan Patent No. I323342 and US Patent No. 7,304,741B2 disclose a rapid fluorescence detection method. This system has fast and simple The detection function of pesticide residues, but the accuracy and reliability of the detection is a big problem
