Title:
GAS CHROMATOGRAPH
Document Type and Number:
Japanese Patent JP2018004526
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gas chromatograph capable of performing an appropriate process according to concentration of a combustible gas in a column oven.SOLUTION: In a gas chromatography 1, a control operation by a unit control part 144 and the control operation by a main body control part 20 are performed and thereby a value of a combustible gas in a column oven which is detected by a concentration detection sensor 143 is gradually compared with a first threshold value and a second threshold value. A different process is performed between the case in which the concentration of the combustible gas in the column oven which is detected by the concentration detection sensor 143 is equal to or more than a first threshold value and the case in which the concentration of the combustible gas which is detected by the concentration detection sensor 143 is equal to or more than the second threshold value. As a result, in the gas chromatograph 1, an appropriate process can be performed according to the concentration of the gas in the column oven.SELECTED DRAWING: Figure 3
