摘　　要：为了解国内实验室己酸乙酯检测能力,国家认监委组织了2010年己酸乙酯检测能力验证活动,大多数实验室取得了满意结果。在本次己酸乙酯检测能力验证中发现:当添加内标物与待测物峰面积相差较大时,会增大检测误差,易造成检测结果离群。本次能力验证中,根据样品中己酸乙酯含量调整内标物添加量的2家实验室获得了满意结果。采用外标法的4家实验室同样取得了满意结果。In order to understand the capability of laboratories in detecting ethyl caproate in liquor,a proficiency testing was organized in 2010;most of laboratories have got satisfactory results.It was found in this proficiency testing that the detection error would be increased if the peak area of ethyl caproate of internal standard was different from that of the tested specimen.Two laboratories have acquired desirable results by adding an internal standard according to the practical situation.Another four laboratories using an external standard could also meet the requirements of this proficiency testing.
