Scope
Main technical content: 1. Detection principle: This method uses direct ionization mass spectrometry. After the sample is extracted, it is detected using a direct ionization mass spectrometer. A data-dependent data acquisition mode is employed for analysis, collecting the first and second mass spectra of the target ions. The test results are then compared with the standard mass spectra of various pesticide residues in the built-in standard library to determine the test results. 2. Performance indicators: - Sensitivity: The sensitivity should be ≥90%. - Specificity: The specificity should be ≥85%. - False negative rate: The false negative rate should be ≤10%. - False positive rate: The false positive rate should be ≤15%.
