The chromatography analysis system further comprising a shutdown execution part (22) configured to start shutdown to finally stop driving of the liquid delivery pump (2) and temperature control operation of the column oven (6) at a time when a predetermined situation occurs, by controlling operation of the liquid delivery pump (2) and the column oven (6), and a column protection temperature setter (24) configured to set a column protection temperature for preventing deterioration of the separation column (12) due to overheating. The shutdown execution part (22) is configured to stop driving of the heater (14) in a state where the liquid delivery pump (2) is driven when the shutdown is started, and then, stop driving of the liquid delivery pump (2) after a temperature of the internal space detected by the temperature sensor (18) becomes equal to or less than the column protection temperature.

摘要： Upon receipt of an analysis initiation instruction, regardless of the necessity of any changes in operation at the time of the analysis initiation, an integrated controller (21) of a system control unit (2) notifies other units (3 to 6) of analysis initiation and changes the luminescent color of a state indication LED (25) to blue which is common to each unit. In a liquid supply unit (3) that received a notification of the analysis initiation, a local controller (34) changes the device status to “RUN” and changes the luminescent color of a state indication LED (35) to blue. This is also applies to other units (4 to 6). Upon completion of the analysis, the integrated controller (21) notifies each unit (3 to 6) of the analysis completion and changes the display color of the state indication LED (25) to green. Each unit (3 to 6) also changes the display color of the state indication LED (35 to 65) to green. With this, a user can intuitively grasp that analysis is in progress and the analysis is completed by looking at the luminescent color of the state indication LED (25 to 65).

摘要： An analysis system includes a setting device, an execution device, a determination device, and a notification device, and analyzes a sample by combining functions of a plurality of units. The setting device sets an analysis condition for each of the plurality of units. The execution device can execute the function of each of the plurality of units prior to the analysis of the sample. The determination device determines whether preparation for starting the analysis is completed for each of the plurality of units based on a comparison between a state of the unit and the analysis condition corresponding to the unit. The notification device notifies an analyst of a determination result by the determination device.

摘要： An autosampler is switched selectively between an injecting mode where a sampling flow path is incorporated into an analysis flow path of a liquid chromatograph and a loading mode where the sampling flow path is not incorporated into the analysis flow path and injects a sample into the analysis flow path at a position farther upstream than a separation column by being switched to the injecting mode with the sample held in the sampling flow path, and includes a clog determiner configured to acquire a sending liquid pressure of a liquid sending pump that sends a mobile phase in the analysis flow path, obtain a variation value of the liquid sending pressure when the injecting mode and the loading mode are switched and determine presence or absence of a clog in a system incorporated into the analysis flow path in the injecting mode based on the obtained variation value.

摘要： 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.

摘要： In the non-volatile storage unit (341) of the local control unit (34) of each unit (3 to 6) configuring an LC system, periodic inspection information, such as the installation date and the next inspection scheduled date, is stored at an appropriate time. When an analysis is carried out, in the system control unit (2) which controls each unit, a periodic inspection notification processing unit (211) collects periodic inspection information from each unit (3 to 7) upon power on or start up, compares the next inspection scheduled date with the current time by the real-time clock (212), and determines a unit for which a periodic inspection notification is required. If there is a unit that requires a periodic inspection notification, a notification request is sent to the unit, and the local control unit (34) of the unit outputs an indication prompting periodic inspection to the display unit (35). As a result, even if the installation times are different for each unit and even if each unit does not have a real-time clock, it is possible to notify a user when a predetermined age of service has passed from the installation time of a given unit.
