摘　　要：辉光放电光谱具有稳定性高、谱线锐、背景小、干扰少、能分层取样等优点,而被广泛应用于金属、合金等导体材料及玻璃、陶瓷、地质等非导体试样的固体成分分析。以GDS850A型辉光放电原子发射光谱仪(GD-OES)为例,归纳了光谱仪联机异常、光谱描迹异常、内循环水水流异常、铰刀不转、新旧电极更换、光电倍增管更换等6个故障实例,通过系统地分析辉光放电原子发射光谱仪结构及工作原理,找到故障原因,并介绍了处理方法。通过这6个故障现象、分析与处理方法,为实验室维护人员遇见类似故障时迅速提供参考并帮助其快速恢复故障,降低仪器故障率,确保其能稳定有效地工作。The glow discharge spectrum has the advantages of high stability,sharp spectral lines,small background,less interference and stratified sampling,so it has been widely used in the solid composition analysis of conductor materials(such as metal and alloy)and non-conductor samples(such as glass,ceramic and geological sample).Taking GDS850A glow discharge optical emission spectrometer(GD-OES)as an example,6 fault cases were summarized,including on-line anomaly,spectral tracing anomaly,internal circulation water flow anomaly,reamer non-rotation,new and old electrode replacement,and photomultiplier tube replacement.By analyzing the structure and working principle of GD-OES,the fault reasons were found,and the treatment measures were introduced.Through these 6 fault phenomena,analysis and processing methods,the reference was provided for the laboratory maintenance personnel who met the similar faults and help them quickly recover the fault and reduce the fault rate of instrument,thus to ensure that it could work steadily and effectively.
