Claim:
1. A sample injector for injecting a fluid into a fluidic path between a high pressure pump and a separation column, the sample injector comprising: a robot arm configured for moving an injection needle, when being connected to the robot arm, between a fluid container containing the fluid and a seat in fluid communication with the fluidic path; the injection needle configured for aspirating the fluid from the fluid container, when the injection needle has been moved to the fluid container, and for injecting aspirated fluid into the fluidic path, when the injection needle is accommodated in the seat, the injection needle forming a part of the fluidic path when accommodated in the seat; the seat configured for accommodating the injection needle and providing fluid communication with the fluidic path; wherein the robot arm is configured for selectively disconnecting the injection needle from the robot arm when the injection needle is accommodated in the seat, such that the injection needle remains a part of the fluidic path after being disconnected from the robot arm; and wherein the robot arm is configured for performing a further task while the injection needle is disconnected from the robot arm.
