Abstract
An analysis apparatus includes an extraction unit that extracts a baseline portion from chromatographic data that is acquired from an apparatus, and a determination unit that determines a normality in the apparatus based on normal chromatographic data and a feature of the baseline portion of the chromatographic data extracted by the extraction unit.
Claims8
An analysis apparatus comprising:
- an extraction unit that extracts a baseline portion whose change is much smaller than that in a peak portion from chromatographic data that is output from a target apparatus of an analysis process;
- and
- a determination unit that determines a normality in the target apparatus of the analysis process based on normal chromatographic data of the target apparatus of the analysis process and a feature of the baseline portion of the chromatographic data extracted by the extraction unit, wherein
- the target apparatus is a Thermal Conductivity Detector,
- the determination unit determines the target apparatus is abnormal when a difference of an inclination of the baseline portion between the normal chromatographic data and the chromatographic data acquired from the target apparatus exceeds a predetermined threshold value, and
- when the determination unit determines the target apparatus is abnormal, the determination unit outputs an alarm or an error message.
