How to do triazophos residue detection? Applicable scenarios for test strip, test card and instrument detection

Triazophos is an organophosphorus insecticide widely used in agricultural production, which has significant effect on the prevention and control of crop diseases and pests such as rice and cotton. However, excessive or unreasonable use may lead to excessive residues in agricultural products, and long-term intake of foods containing residues will pose a potential threat to human health. Therefore, it is crucial to establish a rapid and accurate detection method for triazophos residues. In the field of food safety testing, different detection tools have different application scenarios. Let's learn more about the common methods and application scenarios of triazophos residue detection.

Triazophos residue detection method 1: test strip detection

test strip detection is one of the most widely used rapid screening methods. Its principle is based on the specific binding reaction of antigens and antibodies, and it is determined whether the triazophos residue in the sample exceeds the standard by observing the color development results. Taking the triazophos rapid detection test strip produced by our company as an example, its operation process is simple and convenient: just drop the sample extract into the test strip and add the sample hole, wait for a few minutes, and preliminarily judge the result according to the color development on the test strip. This method does not require professional instruments and is suitable for use in field sites, market stalls and other on-site environments. It is especially suitable for grass-roots agricultural technology promotion stations, market supervision departments and other units to carry out rapid preliminary screening work. It can lock suspicious samples in a short time and provide direction for subsequent detection.

Triazophos residue detection method 2: detection card detection

The detection card is the optimized extension form of the test strip. Usually, the detection reagent is integrated in the card carrier, which further simplifies the operation steps. The triazophos test card produced by Wuhan Yupinyan Bio also adopts colloidal gold marking technology. During testing, you only need to drop the sample liquid into the card slot according to the instructions, and wait for the color development to stabilize before reading the results. Compared with the test strip, the test card is smaller in size, more portable, and the result judgment is more intuitive. It is suitable for scenarios that do not require high operating conditions, such as the self-inspection of raw materials in food production enterprises, and the rapid screening of purchased ingredients by small catering units. Non-professionals can operate independently after simple training, which can effectively reduce the testing cost and time cost of enterprises and help enterprises control the safety of raw materials in a timely manner.

triazophos residue detection method 3: Instrument detection

Instrument detection is a high-precision detection method, usually including high-performance liquid chromatography, gas chromatography-mass spectrometry and other equipment. This type of method requires professional laboratory environment and operation skills. After complex pretreatment of the sample, accurate results can be obtained with the help of the separation and qualitative and quantitative functions of the instrument. Wuhan Yupinyan Bio's rapid detection reagent can also be used as a preprocessing auxiliary tool for instrument detection. For example, use our test strip or test card to quick filter positive samples first, and then confirm the positive samples by instruments, which can greatly improve the detection efficiency. Instrument testing is mainly suitable for third-party testing institutions, large food enterprise laboratories and other scenarios, which can meet the precise analysis needs of regulatory authorities for high-risk samples and ensure the authority and reliability of test results.

To sum up, triazophos residue testing needs to choose the appropriate tools according to the actual scene: test strips and test cards are suitable for rapid screening and on-site testing, and instrument testing is suitable for accurate confirmation and laboratory analysis. Wuhan Yupinyan Bio focuses on the development of food safety rapid detection reagents, and is committed to providing reliable detection solutions for different scenarios to help protect the food safety defense line.
