In the process of residual detection of 97% Epoxiconazole, the following measures can be taken to ensure the accuracy of the test results:
1. Choose a suitable detection method
High performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (HPLC-MS or LC-MS/MS) are effective methods for detecting epoxiconazole residues. These methods have high precision and high sensitivity and can accurately determine the residual amount of epoxiconazole. In addition, ultra-high performance liquid chromatography-tandem mass spectrometry can also be considered. This method combines the QuEChERS method and has the advantages of simplicity, speed, high sensitivity, and good reproducibility. It is particularly suitable for the detection of epoxiconazole in fruits such as citrus.
2. Ensure the representativeness and integrity of the sample
When collecting samples, it should be ensured that the samples are representative and can truly reflect the residues of epoxiconazole in agricultural products or the environment. At the same time, it is necessary to avoid contamination or loss of samples during collection, transportation and storage to ensure the integrity of the samples.
3. Strictly control experimental conditions
During the experiment, the experimental conditions, such as temperature, humidity, light, etc., should be strictly controlled to reduce the influence of external factors on the experimental results. In addition, the accuracy and stability of the experimental equipment should be ensured, and the equipment should be calibrated and maintained regularly.
4. Adopt quality control measures
During the detection process, quality control measures such as blank test, parallel test, spike recovery test can be adopted to verify the accuracy and reliability of the experimental results. At the same time, the test results can also be judged and interpreted by referring to relevant standards or regulations.
By selecting appropriate detection methods, ensuring the representativeness and integrity of samples, strictly controlling experimental conditions and adopting quality control measures, the accuracy of 97% Epoxiconazole in the residual detection process can be ensured.
