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.
