Tea Pesticide Residue Rapid Detection Kit (10)

Tea Pesticide Residue Rapid Detection Kit (10) is designed for the detection of pesticide residue in tea.

Tea Pesticide Residue Rapid Detection Kit (10) is designed for the detection of pesticide residue in tea. This is a color reaction. Compared with blank control test, it is positive result that the white pill doesn’t change any color or it just turns light blue. It indicates there is a high pesticide residue that it doesn’t change any color, and it indicates there is a relatively low pesticide residue that it turns light blue. While it is negative result that the white pill turns blue or has the same color with blank control test card. For those samples of which the results are positive, use other analysis methods to determine the types and concentration of the pesticide.

1, Shake the reaction tubes evenly and avoid shaking acutely.
2, Use centrifuge for green tea during pre-reaction if possible. If filter papers are needed, please use rapid filter papers to shorten the time.
3, Control the speed during using needle tubing to increase the pressure of chromatography column and don’t increase too hard in case collect deeper color filtering liquid which will disturb the result.
4, Avoid dropping too fast when adjusting the PH value. Mix evenly after dropping acid regulator and then test the PH value by PH papers.
5, The reaction should proceed in constant temperature in order to improve the accuracy.
6, This method is suitable for the rapid detection of pesticide residue in dry tea.

This product should be stored in ventilated, dry and dark condition. And it should be kept in the refrigerator at 4 ℃. And the expiration time is one year.
