| 摘 要： | 报道了单用重蒸馏氏倍稀释微量血清后，直接采用ＰＥ４００型原子吸收仪，ＨＧＡ７００型石墨炉，测定血清中铜，锌浓度的新方法。本法用血量少，只用重蒸馏水稀释，标本不易受污染，测定结果稳定，与标准的火焰原子吸收法测定结果有很好的相关性。本法可提高微量法测定铜，锌浓度的准确性，有助于末梢血微量元素测定方法在临床的推广，尤其适用于儿科病儿及需反复测定多种元素的病人。

| Abstract: | A new graphite furnace atomic absorption spectrometric method for direct determination of cop- per and zinc in small volume serum was reported. The volume of serum is only 10 uL. Serum samples are analyzed after 20 - fold dilution with water of ultrapure analytical grade.In ultrapure analytical grade.In contrast to flame AAS,the re- sults obtained ho this graphite furnace AAS are interrelated very well. The method can improve the accu- raey of determination of copper and zinc in small volume serum. It also has an advantage when multiele- ment analysis is required or when the copper or zinc status of infants must be determined. |
