Fully Automatic Pesticide Residue Rapid Detector

Instrument Overview

The fully automatic pesticide residue detector is mainly used for quantitative analysis of pesticide residue components in samples such as vegetables and fruits. The detection system mainly includes functional modules such as project parameters, reagent location, instrument calibration, settings, sample information, result query, initialization, and overall cleaning. It has the characteristics of moderate analysis speed, no cross contamination, few consumables, and open reagents.

It can be widely used for pesticide residue detection in vegetables and fruits in departments such as product quality supervision and inspection, health and epidemic prevention, environmental protection, business management, vegetable wholesale markets, vegetable production bases, supermarkets, shopping malls, pesticide residue monitoring systems, etc.

Basic Principles 

The fully automatic pesticide residue detector is developed using the principles of enzyme inhibition and photoelectric colorimetry. Under certain conditions, organophosphate and carbamate pesticides have inhibitory effects on the normal function of cholinesterase, and their inhibition rate is positively correlated with the concentration of the pesticide. When a certain amount of organophosphorus pesticides or carbamate pesticides are present in the sample extraction solution, enzyme activity is inhibited and the absorbance increases. Based on this rate of change, the residual amount of pesticides in the sample can be determined.
