Abstract：As is known to all, chemiluminescent immunoassay analyzer is a common inspection equipment used by the hospital
inspection department. It has the advantages of large sample size, large measurement items and short testing time. Firstly,
the structure and principle of Liaison chemiluminescence immunoanalyzer were introduced. The apparatus consisted of two
parts: chemiluminescence analysis system and immune reaction system. Two common failures of Liaison chemiluminescence
immunoanalyzer and its maintenance methods were summarized, the reaction cup clamping phenomenon and the liquid detection
error of the rinser were reported respectively. We hope this article will provide references for our peers.
