摘　　要：根据不同人员在不同时间对水中铜的质控样品进行测量得到30组数据,利用Top-down技术控制图法评定ICP-MS方法测定水中铜的不确定度。方法依据是《水质65种元素的测定电感耦合等离子体质谱法》(HJ700—2014),测定质量浓度为40.0μg/L的质控样品,测定均值为40.2μg/L,通过评定不确定度为1.60μg/L。Copper in water samples was determined for quality control by different people in different time. According to 30 sets of data obtained,the uncertainty of ICP-MS method determination of copper in water was evaluated by Top-down technical control chart method. The method was based on ″Water quality-Determination of 65 elements-Inductively Coupled Plasma-mass Spectrometry ″（HJ700-2014）. Copper quality control samples（40.0 μg/L）were analyzed,and the average result was 40.2 μg/L. Measurement uncertainty of copper in water by ICP-MS was 1.60 μg/L.
