在ICP光源与光电直读光谱仪联用时,由于射频波的严重干扰,致使电子测量系统无法正常工作;由于ICP发射的光谱线与电弧发射的光谱线强度相差很大,按一般程序无法用空心阴极灯代替ICP调整出射狭缝,给快速、准确调好狭缝造成了困难。本文对上述两个技术问题进行了研究,提出了消除射频干扰和用阴极灯代ICP调狭缝的简单解决办法。 In the ICP light source and direct reading spectrometer, due to the serious interference of radio frequency, resulting in electronic measuring system does not work; due to ICP emission line and arc emission spectral line intensity difference is very large, according to the general procedure can not be hollow cathode Lamp instead of ICP to adjust the exit slit, to quickly and accurately set the slit caused the difficulty. In this paper, the above two technical issues were studied, and a simple solution to eliminate radio frequency interference and replace the ICP slit with a cathode lamp was proposed.
