Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in the following embodiments, a liquid chromatographic analysis device is taken as an example of a chromatographic analysis device, and a structure in which the device is separated according to function and housed in a housing according to function is used as an example for description. However, it goes without saying that even a A gas chromatographic analysis device or a structure in which the entire device is accommodated in one or more cabinets can also apply the present invention to an opening and closing door for arranging the sample holding container inside.

Abstract

Provided is a highly safe chromatography device that does not sacrifice user-friendliness during the addition and replacement of a sample holding container. The chromatography device has doors 10, 11, a door locking mechanism 15, and a sensor 13 for detecting whether the doors 10, 11 are open or closed. The doors 10, 11 are opened and closed to place a sample holding container 6 and a sample rack 1 in the chromatography device. The door locking mechanism 15 is operated to lock the doors 10, 11 when the sensor 13 indicates that the doors 10, 11 are closed and the analysis of a sample in the sample holding container 6 starts, and is operated to unlock the doors 10, 11 when a return operation and a washing operation terminate after a needle 2, a syringe 9, and other mechanical parts operate. Consequently, the sample holding container can be safely added or replaced without having to perform, for instance, a procedure for executing a pause function.

Description

technical field [0001] The present invention relates to a chromatographic analysis device, and more particularly to a chromatographic analysis device having an opening and closing door for installing a sample holding container inside. Background technique [0002] In a liquid chromatograph or a gas chromatograph, there is known a device in which the devices are separated according to their functions and housed in housings according to their functions, and the respective housings are stacked in height. [0003] For example, in the liquid chromatography analyzer described in Patent Document 1, there is described a structure in which an infusion pump unit, an automatic sampling unit, a column thermostat unit, and a detector unit are separately arranged according to functions. In addition, in the liquid chromatography analyzer described in Patent Document 2, there is described a structure in which a pump device, a sample supply device, a column oven device, and a detection devic...
