Abstract
A gas chromatograph in which the effect of the heat from a column oven on the detection sensitivity of a detector is reduced. The gas chromatograph includes a separation column, a column oven, a heat insulating material covering the outer surface of the column oven, a sheet metal covering the outside of the heat insulating material, a detector including a detection unit disposed outside the sheet metal, a flow path part of the detector communicating with the detection unit and being connected to the separation column through upper surfaces of the sheet metal, the heat insulating material, and the column oven, and an outside seal member interposed between the sheet metal and the heat insulating material on at least the upper surface side of the column oven and blocking an outward fluid movement from an inside of the sheet metal.
