Abstract
A chromatography analysis system includes a liquid delivery pump (), an autosampler (), a separation column (), a column oven (), a detector (). The chromatography analysis system further comprising a shutdown execution part () configured to start shutdown to finally stop driving of the liquid delivery pump () and temperature control operation of the column oven () at a time when a predetermined situation occurs, by controlling operation of the liquid delivery pump () and the column oven (), and a column protection temperature setter () configured to set a column protection temperature for preventing deterioration of the separation column () due to overheating. The shutdown execution part () is configured to stop driving of the heater () in a state where the liquid delivery pump () is driven when the shutdown is started, and then, stop driving of the liquid delivery pump () after a temperature of the internal space detected by the temperature sensor () becomes equal to or less than the column protection temperature.
