摘要:

为了解我国食品检测实验室的β-受体激动剂检测能力，CNAS于2010年委托中国兽医药品监察所组织实施了猪肝中克仑特罗、沙丁胺醇和莱克多巴胺三种β-受体激动剂残留检测的能力验证工作。全国22个省、市、自治区的共68个实验室参加了本次能力验证，采用的测试方法主要是液相色谱-串联质谱法（LC-MS/MS）和气相色谱-质谱法（GC-MS）。结果显示：克仑特罗、沙丁胺醇和莱克多巴胺的实验室满意结果率分别为77.8%、89.6%和92.2%，可疑结果率分别为11.1%、4.17%和0，不满意结果率分别为11.1%、6.25%和7.84%，说明参加能力验证的绝大多数实验室可以准确检测以上三种β-受体激动剂残留。

Abstract:

In order to understand the capability of food testing labs in China for β-agonists testing，the CNAS delegated China Institute of Veterinary Drug Control to organize the proficiency testing(PT) of determination of clenbuterol, salbutamol and ractopamine residues in pig liver(CNAS T0509). 68 labs from 22 provinces/cities/municipalities took part in the PT. LC-MS/MS and GC-MS methods were adopted. The PT showed that 77.8%, 89.6% and 92.2% labs had satisfactory results, 11.1%, 4.17% and 0 labs had questionable results; 11.1%, 6.25% and 7.84% labs had dissatisfactory results for clenbuterol, salbutamol and ractopamine, respectively. In conclusion, the most labs taken part in the PT have good competence in analyzing the three kinds of β-agonists.
