Abstract:
PROBLEM TO BE SOLVED: To provide an analyzer which estimates the sign of the trouble of the analyzer beforehand, prevents the unexpected stoppage and the injustice of a result and is suitable for reducing the time required in maintenance.
SOLUTION: The output data of a detector or the use data of the analyzer is always monitored regardless of the operation of a mechanism during the operation of the analyzer and the sign of the trouble of the analyzer is diagnosed by pursuing a change with the elapse of time. In this analyzer, since the states of all of the detectors provided to the analyzer are always monitored during operation, the trouble of the analyzer is estimated beforehand to prevent the stoppage of the analyzer. Further, since the sign of the trouble of the analyzer is reported to a user or a service man when the sign is confirmed, the non-operation time of the analyzer can be reduced. Furthermore, since the sign of the trouble of the analyzer is diagnosed according to a situation, an excess maintenance can be avoided and a maintenance cost can be reduced.
