How to use the triazophos rapid test strip? The correct operation process of household/primary testing

With the increasing attention to the quality and safety of agricultural products, triazophos, as a commonly used organophosphorus pesticide, has become an important link in the detection of its residues in food to ensure food safety. Household scenarios and grass-roots testing units have an increasing demand for fast and convenient detection tools. The triazophos rapid detection test strip launched by Wuhan Yupinyan Bio has become a practical choice for family self-inspection and grass-roots supervision due to its simple operation and rapid detection. The following is the correct use process of the test strip, which is suitable for non-professionals and grass-roots units for rapid detection.

triazophos rapid test strip preparation before use

need to do three aspects of preparation before use: First, the environment is clean, choose a clean, non-interfering operation table to avoid dust, reagent pollution; Second, sample pretreatment, according to the detection object (such as vegetables, fruits, grains, etc.) to prepare an appropriate amount of samples, if it is a solid sample, need to cut or grind the extract (test strip supporting reagent) to make the extract to ensure that the sample is fully mixed; Third, the test strip temperature, take out the test strip packaging, placed at room temperature (20-30 ℃) environment for 10-15 minutes to avoid the temperature is too low to affect the detection results.

the correct operation process of household and grassroots testing

1. Sampling operation: use a dropper to take an appropriate amount of sample extraction solution (usually 1-2 drops, according to the proportion of the test strip instructions), and slowly drop it along the test strip hole to ensure that the liquid is completely absorbed by the test strip and avoid overflow; 2. Reaction time: After adding the sample, place the test strip at room temperature and let it stand for 5-10 minutes. During this period, avoid shaking or touching the test strip detection area; 3. Result reading: After the reaction is completed, place the test strip flat and observe the color development of the detection area (T-line) and the quality control area (C-line). If only the quality control area is colored, it is a negative result; if both the detection area and the quality control area are colored, it is a positive result (the color depth is related to the concentration, and the darker the color, the higher the concentration may be).

test result judgment and precautions

The result judgment should strictly follow the color development standards: negative results (only C-line color development) indicate that the triazophos residue in the sample does not exceed the detection limit; positive results (both C-line and T-line color development) need to be further reviewed with professional equipment to avoid misjudgment. Precautions include: the test strip should be used within the shelf life, and the unused test strip should be tightly packed immediately after opening; the detection environment humidity should not be too high (recommended

Wuhan Yupinyan Biological's triazophos rapid detection test strip realizes the simplicity of the whole process from sample processing to result reading by optimizing the detection system. It is suitable for scenes such as self-inspection in household kitchens and preliminary screening in grass-roots fields. During use, the operation steps should be strictly followed to ensure the reliability of the test results.
