Abstract
A chromatography system includes a liquid sending pump for sending a mobile phase in an analysis flow path, a sample injector that injects a sample into the analysis flow path, a separation column for separating the sample into components, a column oven for storing the separation column and adjusting a temperature of the separation column to a preset target temperature, a liquid sending controller configured to control an operation of the liquid sending pump, and a column protection flow rate setter configured to set a column protection flow rate. The liquid sending controller is configured to control the operation of the liquid sending pump such that, when the liquid sending pump starts sending the mobile phase, the flow rate of the mobile phase flowing through the analysis flow path does not exceed the column protection flow rate until a temperature in the column oven reaches the target temperature.
