一、等离子体光源的发展简况发射光谱应用于分析化学已有较长的历史了,早在三十年代就已发展成熟。近年来为了满足快速分析的需要,摄谱仪常备有直读装置。但目前常用的粉末粉、块状、棒状固体试样法、以及溶液干渣法,都使用常规电光源激发,其灵敏度、准确度、分析范围、基体干扰和标样等都受到一定限制,影响了光谱分析的进展,因此人们一直在探索 First, the plasma source of the development profile Emission spectroscopy used in analytical chemistry has a long history, as early as the thirties have matured. In recent years in order to meet the needs of rapid analysis, Spectrograph standing device with direct reading. However, the commonly used powdered powders, lumps, rod-like solid sample method and solution dry-slag method are all excited by the conventional electric light source, and their sensitivity, accuracy, analysis range, matrix interference and standard samples are subject to certain restrictions and influences The progress of spectral analysis, so people have been exploring
