| Abstract: | A new method for quantitative analysis of harmful substance sulfotep in chlorpyrifos EC by DB-1 fused silica capillary column with Di-iso-propyl phthalate as the internal standard was established. Analytic conditions were as follows. Column： 30m×0.32mm×0.25μm; column temperature： 170℃; temperatures of injector and detector. 250℃, and carried gas： H2 2.6mL/min. This analytical method is linear and reproducible over the range 0.125-2μg with the correlation coefficient of 0.999 9. The result showed that the standard deviation was 0.005 2, the variation coefficient was 6.56%, and the average recovery was 100.7%. |
