Abstract: A mounting device for mounting a sample separation unit configured for separating, preferably chromatographically separating, compounds in a fluidic sample includes a first fluid connector configured for being mechanically and fluidically coupled with a first fluid interface of the sample separation unit, a second fluid connector configured for being mechanically and fluidically coupled with a second fluid interface of the sample separation unit, and a swivel mechanism configured for swivelling the first fluid connector between a mounting orientation for mounting the first fluid interface of the sample separation unit at the first fluid connector and an alignment orientation for aligning the second fluid interface of the mounted sample separation unit with the second fluid connector for subsequently coupling the second fluid interface with the second fluid connector.

Abstract: A sample injector for a chromatography system is configured for injecting a sample fluid into a mobile phase, and includes a needle and a conduit. The needle is configured for aspirating the sample fluid and includes a needle tip, a needle channel through the needle for guiding the aspirated sample fluid, and a needle opening at the needle tip into which the needle channel opens. The conduit is configured for fluidically coupling with the needle and includes a conduit tip, and a conduit channel through the conduit for guiding fluid and having a conduit opening at the conduit tip. The conduit tip and the needle tip are configured to be pressed against each other for fluidically coupling the conduit channel with the needle channel, with at least a portion of the conduit tip penetrating into the needle opening for providing the fluidic coupling between the conduit and needle channels.

Abstract: A sampling unit includes a needle for aspirating a sample fluid, a housing, and a fitting. The needle includes a needle tip and a needle channel through the needle for guiding the aspirated sample fluid. The needle channel opens at the needle tip. The housing includes a housing cavity and a housing channel opening into the housing cavity. The fitting includes a fitting cavity and a fitting channel. The fitting is configured for sealingly receiving the needle tip into the fitting cavity and for being inserted into the housing cavity, so that the fitting channel on one side fluidically couples to the needle channel and on another side couples to the housing channel.
