人体中微量元素的含量,直接影响着人体健康,已被证明为人体所必须的14种微量元素,用X射线荧光光谱法通过对头发的分析,就可以测定其中8种元素的含量,能为临床和科研提供可靠的数据。本法对发样进行直接测定,具有不损坏原样品的物理和化学性能,分析元素多,速度快,结果准确之特点。选取仪器的最佳工作条件,灵敏度可达0.3ppm,标准偏差为1,变动系数为6%。
Trace elements in the human body, a direct impact on human health, has been shown to be necessary for the human body 14 kinds of trace elements, by X-ray fluorescence spectrometry through the analysis of the hair, you can determine the content of eight elements, can be Clinical and research provide reliable data. This method of direct determination of hair samples, with no damage to the original sample of the physical and chemical properties, analysis of elements, fast, accurate results. Select the best working conditions of the instrument, the sensitivity of up to 0.3ppm, a standard deviation of 1, the coefficient of variation of 6%.
