Beschreibung
Zusammenfassung:	A sample injector (40) configured to introduce a sample fluid into a mobile phase, wherein the mobile phase is to be driven by a mobile phase drive (20) through a separation unit (30) for separating compounds of the sample fluid in the mobile phase, wherein the sample injector (40) comprises a metering device (100) being operable for intaking a metered amount of the sample fluid into the sample injector (40), and a fluidic valve (90) being switchable for operating the sample injector (40) selectively in a filling mode (1300) in which the metering device (100) is switched at least temporarily into fluid communication with the mobile phase drive (20), so that the metering device (100) can be filled via an inlet interface (902) at least partially with the mobile phase being delivered by the mobile phase drive (20) while an outlet interface (904) of the metering device (100) is blocked.
