摘　　要：结合钢研纳克氧分析仪O-3000原理,从样品的制备、分析参数的设置、仪器的校准、载气的纯度、试剂的有效性、空白值的影响等方面讨论了脉冲-红外法测定阳极铜中氧含量时各因素对测定结果的影响。评估了该方法的不确定度分量,并给出了扩展不确定度。结合不确定度分量的大小和影响因素可知:微量、痕量分析时,标准物质定值的准确度对分析结果的影响较大。The impact of oxygen content in anode copper on the results obtained through the pulse infrared method was thoroughly examined.This discussion covered various aspects,including sample preparation,analysis parameter settings,instrument calibration,carrier gas purity,agent effectiveness,blank value influence,combining of the principles of the NCS oxygen analyzer(O-3000).The uncertainty component of this method is assessed,and the expanded uncertainty is provided.Combined with the size and influence factors of the uncertainty component,we can know the accuracy of standard substance's certification in trace amount analysis has a big influence on the whole method.
