Fully automatic pesticide residue detector

Instrument Overview:

The fully automatic pesticide residue detector is mainly used for quantitative analysis of pesticide residues in samples such as vegetables and fruits. The detection system mainly includes functional modules such as project parameters, reagent location, instrument calibration, setting, 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, hygiene 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, organophosphorus and carbamate pesticides have inhibitory effects on the normal function of cholinesterase, and their inhibition rate is positively correlated with the concentration of pesticides. When a certain amount of organophosphorus pesticides or carbamate pesticides are present in the sample extraction solution, enzyme activity is inhibited and absorbance increases. Based on this rate of change, the residual amount of pesticides in the sample can be determined.
