Grain Pesticide Residue Rapid Detection Kit (100)

Cat#
FSD-104
Product Name
Grain Pesticide Residue Rapid Detection Kit (100)
Product Overview
Grain Pesticide Residue Rapid Detection Kit (100) is designed for the detection of pesticide residue in food crops.
Description
Grain Pesticide Residue Rapid Detection Kit (100) is designed for the detection of pesticide residue in food crops. This is a color reaction. Compared with blank control test, it is positive result that the white pill does not change the color or it just turns light blue. It indicates there is a high pesticide residue that the white pill does not change the color. And it indicates there is a relatively low pesticide residue that the white pill turns light blue. While it is negative result that white pill turns blue or has the same color with blank control test card.
Notes
If the white pill in the blank control test doesn’t turn blue, this indicates that the test is abnormal. Maybe it is caused by invalid detecting card or there are something influencing or the quantity of adding sample is not enough. Do the test again after eliminating interference factors.
Storage
It is better to place this product in the refrigerator at 4-10 ℃, and the expiration time is one year.

Scientific Background
Butyrylcholinesterase is sensitive to organophosphorus pesticide. It can catalyze Indophenol acetate to hydrolyze into indophenols(blue) and acetic acid (colorless), while organophosphorus can inhibit the activity of butyrylcholinesterase and change the processes of catalyzing, hydrolyzing and color variation. So organophosphorus pesticide can be detected according to the inhibition rate of the enzyme activity.
Sulfur-containing organophosphorus pesticides are widely used and with high toxicity. Use the enhancer for pesticide residue rapid detecting to pre-treat extracting solution of the detected sample before the oxidation, in order to lower the detection limits and improve the detection sensitivity of this kind of pesticides.
Detection method
Rapid Detection
Features & Benefits
Grain Pesticide Residue Rapid Detection Kit (100) is suitable for the rapid detection of pesticide such as organophosphorus and carbamate. In fact, the card is a kind of enzyme paper made by butylcholinesterase and chromogenic reagent, and it is equipped with enhancer for pesticide residue rapid detecting, so the sensitivity to pesticide is improved highly. This detecting card can meet the requirement of the detection of the lower limit grain pesticide. It is used easily and convenient.
