Japanese Patent JP6794893
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas chromatograph capable of suppressing the start of an analysis operation in a state in which an opening/closing door is slightly opened.SOLUTION: A gas chromatograph 1 includes a column oven 3, an opening/closing door 11, a plate spring 13, and a door side heat insulating material 142. In the gas chromatograph 1, when a gap is formed between the column oven 3 and an end portion of the opening/closing door 11 on an opposite side of a rotation axis B side, an elastic force is applied from the plate spring 13 to the opening/closing door 11. And the opening/closing door 11 is displaced so as to be separated from an opening portion 32A to a position where the opening of the opening portion 32A can be recognized. Therefore, it is possible to suppress preserving the state where a gap is formed between the end portion of the opening/closing door 11 on the opposite side of the rotation axis B side and the column oven 3.SELECTED DRAWING: Figure 6
