1.故障现象及其原因 SPEX 1403型激光拉曼光谱仪经过较长时间使用后,会出现仪器波数扫描精度下降和重复性变坏的现象。 (1) 对已知谱线的测定,谱仪计算机显示的谱线波数值与实际谱线波数值相差变大,可达几十个波数;反复对固定谱线进行测定,
1. Symptoms and their causes SPEX 1403 laser Raman spectrometer after a longer period of use, there will be decline in the accuracy of the instrument wave number scanning and repeatability of deterioration. (1) For the determination of known spectral lines, the difference between the spectral line wave number displayed by the spectrometer computer and the actual spectral line wave value becomes larger, reaching tens of wave numbers; the fixed spectral lines are repeatedly measured,
