Description

Fruit vegetables pesticide residue detection device

Technical Field

The utility model relates to a food safety technical field especially relates to a fruit vegetables pesticide residue detection device.

Background

The pesticide residue refers to that a part of pesticide is not easy to degrade after being applied due to the strong chemical stability, and most or part of pesticide still remains in soil, crops and other environments (a general term for trace pesticide protomer, toxic metabolite, degradation product and impurity). The residual amount is expressed as mg per kg of sample. Pesticide residue is a necessary phenomenon after application, but if the maximum residue limit is exceeded, the pesticide residue toxicity is called pesticide residue toxicity, which has an adverse effect on human preparation or causes toxicity to organisms in the ecosystem through the food chain.

The analysis of pesticide residues in food products is the identification and quantification of target compounds in a complex matrix. The general analysis process of pesticide residue is extraction-purification-detection. The extraction and purification are pretreatment parts, and the pretreatment of the sample not only requires that components to be detected in the sample be extracted as completely as possible, but also removes impurities existing with a target object as far as possible, so that the pollution to a chromatographic column, a detector and the like is avoided, the interference to a detection result is reduced, and the sensitivity and the accuracy of the detection are improved. Therefore, extraction and purification are very important pretreatment steps in the pesticide residue analysis process, and the correctness and reliability of the analysis result are directly influenced.
