一、原理仪器工作原理基于发射光谱分析的基本原理,就是在物质被激发发光的过程中,对光的属性进行测量,从而确定物质各组成元素的含量。试样由激发光源激发而发光,此光经“分光仪”的凹面光栅分光后,形成各元素的线状光谱线。各元素谱线的强弱与元素本身的含量有一定的关系,因此,直接或间接地测定各元素特定谱线的强弱,就可确定其含量(见图)。
First, the principle Principle of the instrument Based on the basic principle of emission spectroscopy, is in the process of the material is excited by light, the properties of light measurements to determine the material content of the various elements. The sample is excited by the excitation light source and emits light. The light is split by the concave grating of the “spectrometer” to form a linear spectral line of each element. The strength of each element line and the content of the element itself has a certain relationship, therefore, directly or indirectly determine the strength of each element of the specific spectral lines, you can determine the content (see Figure).
