Abstract

Describes a method for measuring trace elements Cr, Mn, Co, Fe, Cu, Zn, and Mo in the blood serum using non-flame atomization (KAC 120.1 complex). Optimal conditions for preparing the samples were defined, temperature regimens for analysis of each element selected, and original software permitting automated assays created. The method permits analysis making use of the minimal samples: 0.1 ml per 10 parallel measurements, which is 100 times less than needed for atomic absorption spectroscopy with flame atomization of liquid samples. Metrological characteristics of the method are assessed.

摘要

描述了一种使用无火焰原子化（KAC 120.1络合物）测定血清中微量元素铬、锰、钴、铁、铜、锌和钼的方法。确定了样品制备的最佳条件，选择了每种元素分析的温度方案，并创建了允许自动分析的原始软件。该方法允许使用最少的样品进行分析：每10次平行测量只需0.1毫升，这比液体样品火焰原子化的原子吸收光谱法所需的样品量少100倍。评估了该方法的计量特性。
