由于发射光谱,特别是使用ICP光源时、含有众多的光谱线,需要有较高的色散率和分辨率、且波长覆盖范围较宽的分光系统以供使用。特别是对于那些具有复杂光谱基体的样品如镧系、锕系元素、地质样品、黑色金属、高温合金等等来说,使用一般市售一米左右的ICP发射光谱仪时,谱线干扰在所难免,需要用复杂的方法或软件来避免或扣除这类干扰。如果能采用色散率和分辨率都比常规光谱仪高得多、而且有足够的波长覆盖范围和光强的光谱仪,则不但 Due to the emission spectrum, in particular the use of ICP light sources, which contain a large number of spectral lines, a spectroscopic system with a higher dispersion and resolution and a broader wavelength coverage is required. Especially for samples with complex spectral matrices such as lanthanides, actinides, geological samples, ferrous metals, superalloys and the like, spectral line disturbances are unavoidable when using commercially available one meter or so ICP emission spectrometers , Complex methods or software are required to avoid or eliminate such interference. If spectrometers with both dispersion and resolution are much higher than conventional spectrometers and have adequate wavelength coverage and light intensity,
