Sodium 4-Chlorophenoxyacetate in Bean Sprouts Colloidal Gold Rapid Detection Card Instruction Manual

Sodium 4-chlorophenoxyacetate in bean sprouts Colloidal gold rapid detection card Instructions for use

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 antibodies and antigens on the detection line (T-line) in the test strip, resulting in changes 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) Knives, scissors, stickers and other tools should be cleaned to avoid cross contamination.

(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 should match the corresponding experimental equipment and wear the necessary experimental equipment (white clothes, gloves, masks, etc.).

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

(3) After the experiment, keep the laboratory clean 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 be disposed of 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.

storage conditions and valid period

(1) Original packaging: dry storage at 2-30 ° C away from light, do not freeze, valid period 12 months.

(2) After unpacking: Use immediately after unpacking the test card, do not freeze.
