Fully automatic pesticide residue rapid detector

Overview:

The fully automatic pesticide residue rapid 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 position, instrument adjustment, settings, sample information, result query, initialization, and full disk cleaning. It has the characteristics of moderate analysis speed, no cross contamination, few consumables, and open reagents.

The fully automatic pesticide residue rapid detector can be widely used in product quality supervision and inspection, health and epidemic prevention, environmental protection, industrial and commercial management, vegetable wholesale markets, vegetable production bases, supermarkets, shopping malls, pesticide residue monitoring systems and other departments for the detection of pesticide residues in vegetables and fruits.

Basic principle

The fully automatic pesticide residue rapid detector is developed based on the principle of enzyme inhibition and photoelectric colorimetry. Under certain conditions, organophosphorus and carbamate pesticides have an inhibitory effect on the normal function of cholinesterase, and the 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 extract, the enzyme activity is inhibited and the absorbance becomes higher. According to the change rate, the residual amount of pesticide in the sample can be determined.
