资料摘要
资料下载The ITQ 700 GC-ion trap MS was thoroughly evaluated and showed excellent accuracy at low concentrations for a large number of pesticide residues analyzed in green tea. Using the instrument’s MSn functionality allows the user to identify, confirm, and quantify in one analytical run. The injector demonstrated low endrin and DDT breakdown (< 15%) on a daily basis, proving that the system can analyze active compounds without the need for continual, expensive, and time-consuming maintenance. Calibration curves for most pesticides studied met a linear least squares calibration with a correlation coefficient of R2 > 0.995. The Method Validation Study generated an average % RSD of 10.8% for five replicate analyses at 37.5, 75, 150, 225, 600, or 1200 ng/g and a calculated average LOD of 14 ng/g in tea based on 7 replicate analyses of 7.5, 15, 37.5, 75, or 300 ng/g These results demonstrate that the ITQ 700 can comply with international regulations for the control of pesticides in tea.
