摘要

以燕麦、大麦、小麦、玉米2种配方饲料为研究对象，在13个实验室开展了hplc -MS/MS法测定饲料中氯苯胺的合作研究。准确度为75.3 ~ 87.0%，重复性和再现性相对标准偏差(RSDr和RSDr)分别在7.3%和33%以内，HorRat值为0.39 ~ 1.5。饲料中氯苯胺的检出限为0.008 mg/kg，定量限为0.003 mg/kg。该方法可用于饲料中氯苯胺的检测。

[Collaborative Study of an LC-MS/MS Method for Determination of Chlorpropham in Feeds].

A collaborative study for validating the determination method of chlorpropham in feeds by LC-MS/MS was conducted in 13 laboratories using 2 kinds of formula feeds, oats, barley, wheat, and corn. The resulting trueness ranged from 75.3 to 87.0%, repeatability and reproducibility in terms of relative standard deviation (RSD_r and RSD_R) were within 7.3% and 33% respectively, and the HorRat values ranged from 0.39 to 1.5. The limit of detection and limit of quantitation of chlorpropham in feed ware 0.008 mg/kg and 0.003 mg/kg, respectively. This method was thus validated as useful for inspections of chlorpropham in feed.
