Sodium 4-chlorophenoxyacetate in bean sprouts Colloidal Gold Rapid Detection Card Instruction Manual

Product Number: YB095C01K

Summary

4- Sodium 4-Chlorophenoxyacetic acid sodium sal is mainly used as a plant growth regulator. In the growth of bean sprouts, sodium 4-chlorophenoxyacetate is widely used. Long-term consumption will cause accumulation harm to the human body, carcinogenic and teratogenic effects.

Detection Principle

This product adopts the principle of competitive inhibition immunochromatography. Sodium 4-chlorophenoxyacetate in the sample binds to the specific antibody labeled with colloidal gold to inhibit the binding of the antibody and the antigen on the detection line (T line) in the test strip, resulting in a change in the color depth of the detection line. Regardless of whether the sample contains the substance to be tested, the quality control line (C line)

will develop color to show that the detection is valid.

Scope of application

This product is suitable for qualitative detection of sodium 4-chlorophenoxyacetate residues in fresh bean sprouts samples.

Note: The type of test sample refers to the national standard GB2763-2021.

precautions

(1) Before each sample, the knife for shredding the sample needs to be cleaned to avoid cross-contamination.

(2) The test environment temperature should be controlled at 18~ 30 ℃. If the temperature is too high or too low, it will affect the test results.

(3) Please follow the test steps to test. Do not touch the color-developing area of the test strip during operation. Avoid direct sunlight and direct blowing of electric fans.

(4) Please use the sample as soon as possible after processing. If the time is too long, you need to re-process the sample for re-testing.

(5) 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 judgment of experimental results.

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

(7) This product is a one-time product. Please do not reuse or mix test cards from different batches.

(8) It is recommended to retest when positive results appear. The test results of this product are for reference only. If you need to confirm, please refer to the relevant national standards and methods.

(9) When evaluating the product, if you need to directly test the standard product, you need to use the special dilution in the kit.

(10) 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 needs to be stored in a place that is not easy for children to contact, and do not eat the equipped reagents.

(3) All items used in the experiment should be properly disposed of after application, and should not be exposed to children.

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

(5) Collect the experimental waste separately, and it is recommended to dispose of it as medical waste.

(6) Do not eat the reagents equipped.
