Transport device

A transport device for transporting an analyte from a gas chromatograph into a detector has a transfer line, connectable on its outlet side to the detector, and connected on its inlet side to a connection part which is connectable to a separating column of the gas chromatograph. An auxiliary gas connection feeds an auxiliary gas into the transfer line. Gas flowing out of the separating column into the transfer line is mixable with the auxiliary gas feed through the auxiliary gas connection, and a temperature profile which falls along the transfer line toward the detector is produced during measurement by a heating device acting on the transfer line.
