description A connecting capillary tube is arranged in a branch coupling and is shorter than the guide bores into which separation columns are introduced. The ends of the separation columns slide automatically over the ends of the connecting tube. The connecting tube is sealed with metal disks instead of graphite ones. The flush gas conduits are so arranged that the dead spaces can be well flooded, reducing adsorption of sample and increasing the performance of the gas chromatograph.
