A device and method for rapidly detecting pesticide residues in fruit and vegetable products

Abstract

The invention discloses equipment for rapidly detecting pesticide residues in fruit and vegetable products. The equipment mainly consists of a to-be-tested sample liquid preparation device, an allocation device, a conveying device, to-be-tested sample liquid storage devices, a rotating disc and a detection analysis device, wherein the to-be-tested sample liquid preparation device is connected withthe allocation device through a tube connector; a to-be-tested sample liquid is allocated into the to-be-tested sample liquid storage devices and is further transferred to the rotating disc through the conveying device; the detection analysis device is positioned on the right side of the rotating disc; the detection analysis device is internally provided with optical detection equipment and a host computer; the optical detection equipment is connected with the host computer through a conduction lead. By adopting the equipment, crushing, extraction, purification, sample liquid preparation, sample liquid allocation, sample liquid conveying and sample liquid detection are integrated, a high automation degree is achieved, the operation can be implemented rapidly and conveniently, pesticide residues on a sample to be tested can be rapidly and effectively detected, relatively detection results can be achieved, pesticide residues of a plurality of different samples to be tested can be detected continuously within a short time, and thus high efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of pesticide residue detection devices, in particular to a device and method for quickly detecting pesticide residues in fruit and vegetable products. Background technique [0002] my country is a large agricultural country, and the production and use of pesticides are very common in my country, especially the highly toxic organophosphorus and carbamate pesticides, which are currently the largest pesticides produced and used in my country. The large-scale use and abuse of pesticides, coupled with the lack of effective and rapid on-site detection methods for pesticides in the society, lead to inadequate supervision, which makes the phenomenon of excessive pesticide residues in vegetables, fruits and other agricultural products in my country very serious, and also leads to pesticides in our country. Pollution of surface water and groundwater. On the other hand, with the continuous improvement of people's livin...
