Abstract

PURPOSE: To make correct analyses at any time by detecting the variation of characteristics of an analysis unit and by performing calibration when the variation exceeds its allowable value.
CONSTITUTION: In the program controlling the operation of an analysis part, the program is provided withi detects and compares charactersitcs of an analysis unit to the last ones to detect the change and stores a memory part with the characteristics, in addition the program that detects whether the detected change of the analysis unit reach its allowable value is provided. Further, the program that generates calibration command 26 when the change exceeds the allowable value is provided. Once the calibration command is output, the reading of sequence table 19 is changed over to an analysis of standard gas, which is analyzed to correct and rewrite a parameter needed for an analysis in parameter table 18.
