Method-performance Studies of Notified Analytical Method for Chinomethionat

摘要

Method-performance studies were conducted for the notified revised analytical method of chinomethionat in agricultural products by interlaboratory study. Six laboratories analyzed unpolished rice, cabbage, squash, lettuce and orange spiked with 0.1μg/g of chinomethionat in replicate. Mean values of recovery from the 5 crops ranged from 90.2 to 100.5/100. Repeatability relative standard deviations ranged from 4.4 to 7.7/100 and reproducibility relative standard deviations ranged from 10.9 to 17.1/100. The detection limits were 0.003-0.012μg/g.
