Extending the service life of the pesticide residue detector should be started from the daily use and daily maintenance, mainly by the following aspects:
1. The environment where the pesticide residue detector is placed should be kept dry, dust-free, and free of vibration. In order to prolong the service life of the instrument, if the instrument is idle for a long time, the rechargeable lithium battery should be removed and stored in a dry place for proper storage.
2. When using the Pesticide Residue Tester for the first time, ensure that the lithium battery is fully charged. When installing a lithium battery, the user should pay attention to the polarity of the battery plug.
3. If the pesticide residue detector instrument indicator light is off, it means that the current battery power is too low, it should be charged in time, or the instrument will automatically shut down.
4. The internal passage of the pesticide residue detector instrument should be kept clean and free of dust. If there is dirt, it should be wiped clean.
5. The instrument should be wiped clean with dry soft cotton cloth after use. If it is not used for a long time, the instrument should be stored in a dry box in the instrument box to ensure the instrument has good accuracy, reliability and long service life.
How to extend the life of the pesticide residue detector?
China's pesticide residue detection technology started late. At present, most commonly used residue detection methods are traditional analysis methods. This method has the solvent extraction method used is time-consuming, laborious, and easy to pollute the environment; detection method has low sensitivity, low extraction and purification efficiency, it is difficult to adapt to the current analysis of pesticide residues, and can not meet international limited requirements, especially the needs of export inspection; the lack of Wide range of applications, simple pre-processing, highly efficient and sensitive methods, greatly increase the workload and analysis time, and bring great difficulties to the detection of large quantities of samples. Therefore, the application of pesticide residue detector is also more worthy of recommendation. With the further development and application of ultra-high-efficiency pesticides and the rapid increase in the number of sample detection, the sensitivity, specificity, and rapidity of pesticide residue analysis and detection technology are higher. The request has also prompted some new and advanced pesticide residue analysis technologies to be developed and developed in succession. The application of these high and new technologies has greatly improved the qualitative ability of pesticide residue detection, as well as the sensitivity and quantity of detection, thereby expanding the scope of detection coverage. .
