Chlorpyrifos Colloidal Gold Rapid Detection Card Instruction Manual

Chlorpyrifos Colloidal Gold Rapid Detection Card Instruction Manual

Product Number: YB085C01K

Summary

Chlorpyrifos (Chlorpyrifos), also known as amidophos, is a broad-spectrum insecticide, which is highly toxic to aquatic organisms and may have long-term adverse effects on the aquatic environment.

Detection Principle

This product adopts the principle of competitive inhibition immunochromatography. Chlorpyrifos in the sample binds to the specific antibody labeled with colloidal gold, inhibits the binding of the antibody to the antigen on the NC film detection line (T line), resulting in the change of the color depth of the T line; according to the color depth of the T line and the quality control line (C line).

Scope of application

This product is suitable for qualitative detection of chlorpyrifos residues in fresh vegetables, fruits and other samples.

Note: The type of test sample refers to the national standard GB2763.

Specific

This product was used to test carbendazim, triazole and triazolone samples containing 10mg/kg, and the results were negative.

The product was used to test the samples containing 0.04 mg/kg chlorpyrifos methyl and 0.06 mg/kg propionate bromide, and the results were positive.

(2) Sample requirements: Avoid spoilage and deterioration of the sample; Avoid large pieces of soil (can be thrown off or wiped with other clean items).

(3) Before testing, it is recommended that the sample be fully stirred and mixed (if the sample is less, the representative part should be taken, and then the sample should be weighed), so that the test results can more realistically reflect the actual drug residue of the sample.

(4) The detection environment temperature should be controlled at 20~ 30 ° C. If the temperature is too high or too low, it will affect the test results.

(5) Please follow the detection steps for testing. Do not touch the color-developing area of the test strip during operation, and avoid direct sunlight and electric fan direct blowing.

(6) The sample solution to be tested needs to be clarified, otherwise it will easily lead to abnormal phenomena such as inconspicuous color development, which will affect the

(7) Products that have expired or damaged aluminum foil bags cannot be used. Please use the test card immediately after unpacking.

(8) Please use it as soon as possible after the sample is processed. If the time is too long, you need to reprocess the sample for re-testing.

(9) When positive results appear, re-testing is recommended. The test results of this product are for reference only. If you need confirmation, please refer to the relevant national standards and methods.

(10) When adding standard verification, the standard solution solvent generally chooses methanol, and the final sample is recommended to add a scalar amount of 10-50 μL.

(11) When directly testing the standard, use the solvent kit supporting the extract, and the amount of organic solvent is controlled within 1%. Tap water, distilled water, purified water or deionized water cannot be used as a negative control.

Safety instructions

(1) The experiment needs to match the corresponding experimental equipment and wear the necessary experimental equipment (white clothes, gloves, masks, etc.).

(2) The test kit should be properly stored and placed in a place that is not easy for children to contact.

(3) Keep the laboratory clean and tidy after the experiment and the air circulation of the experimental environment.

(4) This product is a one-time product, and it should be properly disposed of after the test. The experimental waste is collected separately. It is recommended to dispose of it according to the medical waste.

(5) The reagents involved in this product are safe and reliable, and do not contain carcinogenic, highly toxic, flammable, explosive, and highly corrosive reagents, but should not be eaten.
