Abstract：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.
