Device storage structure for fluid chromatograph
A storage container includes a casing and a bi-parting door. The casing has an opening and stores a device to be used in a fluid chromatograph. A door of the bi-parting door includes a frame member and a cover member. The frame member includes an upper frame and a lower frame. The upper frame and the lower frame are provided at the casing to be turnable around a turning axis and be spaced apart from each other on the turning axis. The cover member is configured to be attachable to and detachable from the frame member and partially cover the opening when the door is closed. A space is formed between the upper frame and the lower frame.

CHROMATOGRAPHY ANALYSIS SYSTEM
A chromatography analysis system includes a liquid delivery pump (2), an autosampler (4), a separation column (12), a column oven (6), a detector (8). 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.
LIQUID CHROMATOGRAPH
A liquid chromatograph includes a liquid feeding portion, a sample injection portion, a separation column, a first temperature adjustment device which raises temperature of the separation column to a first temperature, a detector, a second temperature adjustment device which is provided upstream of the separation column and adjusts temperature of a mobile phase to a second temperature lower than the first temperature, and a control device which controls at least one of the liquid feeding portion and the second temperature adjustment device. The control device controls at least one of the liquid feeding portion and the second temperature adjustment device such that the mobile phase adjusted to the second temperature is fed to the separation column before a next sample is injected after separation of sample components by the separation column ends.

Chromatograph having operation controller that causes automatic purging in a case of detection failure
To make it easy to address the case in which a chromatograph does not appropriately operate. A chromatograph (liquid chromatograph 100) for analyzing a sample by supplying an eluent and the sample and separating a component contained in the sample to detect the component, the chromatograph including: a detection portion (controller 170) configured to detect a fault in the analysis; and an operation controller (controller 170) configured to cause a constituent element related to the analysis to perform at least one of an operation for identifying a factor of the fault and an operation for avoiding the fault.

GAS CHROMATOGRAPH DEVICE
Provided is a gas chromatograph device capable of appropriately determining that a temperature of an entirety of a heating target has stabilized after cooling the heating target in a column oven to a target temperature after a temperature-rising analysis. A gas chromatograph device capable of performing a temperature-rising analysis cools an inside of a column oven by a cooling mechanism. When a detection temperature by a temperature sensor for detecting a temperature of the heating target has reached a target temperature after the inside of the column oven has been cooled, the heating target is heated by a heater. Upon reaching of the detection temperature of the temperature sensor to the target temperature, it is determined whether or not the temperature of the entirety of the heating target has stabilized based on power consumption of the heater.

LOW THERMAL MASS GC MODULE
A system and method for performing field-portable GC/MS measurements for the rapid sampling and measurement of high temperature boiling semi-volatile organic compounds in environmental samples, wherein other column bundles have cold spots that may prevent high temperature boiling semi-volatile components from eluting the GC column, this new design may eliminate those cold spots on the GC column.
