SAMPLE INJECTOR WITH DISCONNECTABLE INJECTION NEEDLE

摘要

A sample injector (500) for injecting a fluid into a fluidic path, wherein the sample injector (500) comprises a robot arm (502) configured for moving an injection needle (506), when being connected to the robot arm (502), between a fluid container (510) containing the fluid and a seat (508) in fluid communication with the fluidic path, the injection needle (506) configured for aspirating the fluid from the fluid container (510), when the injection needle (506) has been moved to the fluid container (510), and for injecting aspirated fluid into the fluidic path, when the injection needle (506) is accommodated in the seat (508), and the seat (508) configured for accommodating the injection needle (506) and providing fluid communication with the fluidic path, wherein the robot arm (502) is configured for selectively disconnecting the injection needle (506) from the robot arm (502) when the injection needle (506) is accommodated in the seat (508), and wherein the robot arm (502) is configured for performing a further task while the injection needle (506) is disconnected from the robot arm (502).
