Sample Injector with Conduit Tip Penetrating Into Needle Opening

A sample injector for a chromatography system, the chromatography system comprising a mobile phase drive and a separation unit, wherein the mobile phase drive is configured for driving a mobile phase through the separation unit, and the separation unit is configured for chromatographically separating compounds of a sample fluid in the mobile phase, the sample injector being configured for injecting the sample fluid into the mobile phase and comprising:

• a needle configured for aspirating the sample fluid, wherein the needle comprises a needle tip on one end, a needle channel through the needle for guiding the aspirated sample fluid, and a needle opening at the needle tip with the needle channel opening into the needle opening;
• and
• a conduit configured for fluidically coupling with the needle, wherein the conduit comprises a conduit tip on one end, and a conduit channel through the conduit for guiding fluid, and the conduit channel has a conduit opening at the conduit tip,
• wherein 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, and at least a portion of the conduit tip is penetrating into the needle opening for providing the fluidic coupling between the conduit channel and the needle channel.
