<P>PROBLEM TO BE SOLVED: To provide a method and a system for circulating the air. <P>SOLUTION: A gas chromatography system includes a double-wall oven which is coupled to a sample introduction device and constituted so as to accept a chromatography column in a space in the double-wall oven, in which the double-wall oven is constituted so as to provide substantially fixed temperature to a space between analysis stages of the gas chromatography system, the double-wall oven includes an inner wall and an outer wall, is constituted so as to flow the air between the inner wall and the outer wall, the double-wall oven further includes: an intake port; an exhaust port; and a fan constituted so as to adjust temperature in an oven space. The gas chromatography system further includes a controller constituted so as to adjust an opening degree of at least one of the intake port and the exhaust port and to control speed of the fan based on the opening degree of at least one of the intake port and the exhaust port, and also includes a detector to be coupled to the double-wall oven. <P>COPYRIGHT: (C)2013,JPO&INPIT |
