What are the precautions for using a portable pesticide residue rapid analyzer

Portable pesticide residue rapid detection instrument is a convenient and easy to carry instrument that can quickly detect pesticide residues in food. However, when using this instrument, some precautions need to be taken to ensure its normal operation and accurate detection.

Firstly, before using a portable pesticide residue rapid analyzer, it is necessary to carefully read the instructions and operate according to them. To avoid errors or damage to instruments caused by improper operation. At the same time, it is necessary to understand the various functions and parameters of the instrument, and choose the appropriate instrument model and parameter settings according to different detection needs.

Secondly, before conducting sample testing, it is necessary to preprocess the test sample. This includes cleaning the surface of the sample, removing impurities, and performing operations such as crushing or homogenizing. During the pre-treatment process, attention should be paid to preventing secondary contamination of the sample and ensuring its representativeness and authenticity.

When conducting testing, it is necessary to prepare reagents and sample solutions according to the instructions. Pay attention to the expiration date and storage conditions of reagents, and avoid using expired or contaminated reagents. At the same time, attention should be paid to the dosage and preparation ratio of reagents to ensure the accuracy and representativeness of the sample solution.

During the detection process, it is necessary to control the reaction time and temperature conditions well. Select the appropriate reaction time and temperature according to the requirements of the instrument to ensure sufficient and accurate reaction. At the same time, it is necessary to pay attention to the reaction and data changes of the instrument, adjust parameters in a timely manner, or retest.

Finally, after the detection is completed, the data needs to be processed and analyzed. Pay attention to the credibility and error range of the data, and avoid using invalid or unreliable data. At the same time, it is necessary to record and organize the data to facilitate subsequent traceability and analysis.

In addition to the above precautions, it is also necessary to pay attention to the following points. Firstly, it is necessary to regularly calibrate and maintain the instrument to ensure its normal operation and effectiveness. Secondly, it is necessary to avoid the instrument being affected by strong vibrations or impacts to prevent damage or errors. At the same time, it is necessary to pay attention to the power and battery condition of the instrument to avoid the inability to perform normal detection due to insufficient battery or power failure.

In summary, the portable pesticide residue rapid detection instrument is a convenient and fast food safety detection tool. When using this instrument, attention should be paid to operating standards and maintenance to ensure its normal operation and accurate detection.
