With the modernization of agriculture and animal husbandry, the use of agricultural and veterinary drugs has generally improved production efficiency, but it has also brought about safety hazards of drug residues in agricultural and livestock products. In order to ensure the food safety of consumers, the rapid detection instrument for pesticide residues has become an important tool for detecting the presence of excessive drug residues in agricultural and livestock products. The following will provide a detailed introduction to the usage method and precautions of the rapid detection instrument for agricultural and veterinary drug residues.

1、 Usage method

　　Rapid detection instrument for agricultural and veterinary drug residuesThe operation is usually relatively simple, and users only need to follow the following steps to complete the detection:

1. Prepare samples:

-Liquid samples: For liquid samples such as fruit, vegetable or animal juices, milk, etc., they are first sampled and filtered to remove impurities.

-Solid samples: Solid samples such as meat, vegetables, grains, etc. need to be ground, juiced, or extracted to ensure uniformity and adequacy of the sample.

-According to the testing requirements, the sample can be diluted appropriately.

2. Add extraction solution:

For some drug residue detection, the instrument may require the use of specialized extraction solutions for drug dissolution or decomposition. According to the instructions, add an appropriate amount of extraction solution, mix thoroughly, and then precipitate or filter.

3. Choose the detection module and startup instrument:

Select the corresponding testing module based on the category of agricultural and veterinary drugs to be tested. The rapid detection instrument for agricultural and veterinary drug residues is usually equipped with different detection modules to detect different drugs. After selecting the appropriate module, place the sample in the designated position of the instrument and start the instrument for testing.

4. Read result:

The instrument will quickly obtain test data through built-in sensors or test paper reactions, usually taking a few minutes to obtain results. The instrument will display the specific value of residual amount or indicate whether it exceeds the standard through color change/numerical display.

5. Recording and cleaning:

After the detection is completed, record the results and perform data analysis or report output as needed. Clean the instruments and testing pipelines to avoid sample contamination and residual effects on subsequent testing.

2、 Precautions

1. Strictly follow the instructions:

Different models of detectors and reagents have different operating requirements, and must be used according to the instrument's operating manual to avoid inaccurate test results caused by operational errors.

2. Sample preparation:

The preparation of samples is crucial for testing, as it must ensure that the samples are fresh, free from contamination, and the preparation process is thorough. Especially for the extraction of solid samples and the filtration of liquid samples, attention should be paid to accuracy.

3. Choose the correct detection mode:

Instruments usually have multiple detection modes, and corresponding modes need to be selected for different types of agricultural and veterinary drugs. If the wrong mode is selected, it can result in inaccurate results or inability to detect the target substance.

4. Avoid cross contamination:

During the sample processing, cross contamination between different samples should be avoided. When using different test tubes and tools, ensure thorough cleaning, especially during multiple tests, to prevent drug residues from affecting subsequent results.

5. Regularly calibrate instruments:

To ensure the accuracy of the instrument, regular calibration is necessary. The calibration process should use standard drug solutions to verify whether the instrument can accurately detect residues of known concentrations.

6. Reagent storage:

The reagents used in the testing instrument should be stored in a dry and cool place to avoid the influence of high temperature and humid environment on the reagents. Expired or damp reagents can reduce detection accuracy.

7. Data recording and tracing:

The test results should be recorded in detail for subsequent traceability and statistical analysis. Especially in food safety monitoring, maintaining the accuracy and completeness of data is crucial.

3、 Summary

As an important tool for ensuring the quality and safety of agricultural and livestock products, the rapid detection instrument for pesticide residues not only improves detection efficiency and accuracy, but also reduces the impact of human errors. Scientifically and reasonably using this instrument, while paying attention to the above operational details and maintenance measures, can not only ensure the accuracy of test results, but also provide strong support for food safety supervision and agricultural production. It is the "guardian" of consumer health and a reliable assistant for agricultural development.
