Abstract
In this device, for sweeping and injecting samples into the separation column of a chromatography apparatus, the separation column is secured to an opening connecting with a conduit which feeds a stream of carrier liquid to the device. The device subdivides a stream of carrier liquid into a primary stream and a secondary stream and feeds the primary stream over the entire cross section of the entrance to a separation column. Simultaneously feed of the secondary stream axially to the entrance of the separation column is performed while introducing the sample into the secondary stream. The device is usable particularly in liquid-phase chromatography.
