Thiamethione Colloidal Gold Rapid Detection Card Instruction Manual

Thiamethione Colloidal Gold Rapid Detection Card Instruction Manual

Product Number: YB083C01K

Summary

Thiamethione is a neonicotinoid insecticide, which mainly acts on the nervous system of insects. It can selectively bind to the nicotinic acetylcholine receptor in insects, block the transmission of nerve signals, and finally kill pests. It has the characteristics of high efficiency, strong internal absorption, long shelf life, and high safety.

Detection Principle

This product adopts the principle of competitive inhibition immunochromatography. The specific antibody labeled with colloidal gold in the sample binds to the antibody and 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 development depth of the T-line and the C-line judgment result.

Uses

for the initial screening of thiamethione content in fresh vegetables and fruits. The minimum detection limit of

samples

0 mg/kg (ppm)

cross-reactivity and product performance

cross-over rate with imidacloprid is about 1.5%, and cross-over rate with furomefam, amidacloprid, thiamethiazine, and polymycin is less than 0.5%.

(1) tools such as knives, scissors and stickers 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 erased 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 accurately reflect the actual drug residue of the sample.

(4) The detection environment temperature should be controlled at 17~ 30 ° C. Too high or too low temperature 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 insignificant color development, which will affect the judgment of the experimental results.

(7) expired or aluminum foil bag damaged products can not be used, please use the test card immediately after unpacking.

(8) Please use the sample as soon as possible after processing, 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 scalar amount at 10-50 μL.

(11) When directly testing the standard, use the solvent kit supporting the extract, and the amount of organic solvent added 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 the air circulation of the experimental environment after the experiment.

(4) This product is a disposable 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 they should not be eaten.

storage conditions and valid period

(1) Original packaging: dry storage at 4-30 ° C, do not freeze, valid period 12 months.

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