How to choose a pesticide residue rapid analyzer? What styles are available
The inspection principle is the same:cholinesterase,which is highly sensitive to pesticides,can catalyze the hydrolysis of indophenol acetate to acetic acid and indophenol(blue).Due to the inhibitory effect of organophosphorus and carbamate pesticides on the activity of cholinesterase,the catalytic hydrolysis process is changed,thereby determining the residual situation of pesticides
1.Portable pesticide residue detector card,which distinguishes whether there are pesticides exceeding the standard by heating the pesticide residue card to react and color display
2.Desktop spectrophotometer pesticide detector,which automatically calculates the inhibition rate by computer based on the inhibitory effect of pesticides on cholinesterase activity,printing 50%as exceeding the standard
3.Desktop 96 channel detector,similar to 2's convenient upgrade for inspection
4.The new digital intelligent pesticide residue detector is actually an upgraded product of 1.It displays whether the pesticide exceeds the standard with the naked eye,and 4.The computer automatically compares colors to distinguish whether the pesticide exceeds the standard and can print the results
