Fault maintenance cases of glow discharge optical emission spectrometer
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,ce-ramic 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,inter-nal circulation water flow anomaly,reamer non-rotation,new and old electrode replacement,and photo-multiplier tube replacement.By analyzing the structure and working principle of GD-OES,the fault rea-sons 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 en-sure that it could work steadily and effectively.
