Abstract

PURPOSE: To achieve the miniaturization and higher performance of the duplex type detector by integrally constituting a heat conductivity type detector and other detector and communicating the passes thereof with a straight pass.
CONSTITUTION: In the duplex type detector for gas chromatograph comprising series connecting plural detectors of different detection characteristics to the carrier gas pass after the column of the gas chromatograph, the plural detectors are constituted by a heat conductivity type detector (TCD) 6 and a kind other than TCD for flowing the carrier gas effluent therefrom, e.g., hydrogen flame ionization detector (FID) 8, the gas outlet of the TCD 6 and the gas inlet of the FID 8 of the rear stage being connected by a linear pass. Since the pass flowing from the TCD 6 to the FID 8 is linear and is extremely short, diffusion of the sample components measured by the TCD 6 is obviated and the separating condition of the sample components is not degraded. In addition the constitution becomes simple and smaller in size.
