    Abstract: A configurable injector for injecting a fluidic sample in a separation path of a sample separation apparatus includes a sample accommodation volume for accommodating the fluidic sample to be injected into the separation path, a valve arrangement fluidically couplable with the separation path, fluidically coupled with the sample accommodation volume, and being controllable for injecting the fluidic sample into the separation path, an input interface configured for receiving input data indicative of an injection profile of an injector to be emulated by the configurable injector, and a control unit configured for controlling the configurable injector, in particular the valve arrangement, so that the configurable injector is operated in accordance with the injection profile to thereby emulate the injector to be emulated.

    Abstract: A sampling unit includes a needle for aspirating a sample fluid, a housing, and a fitting. The needle includes a needle tip and a needle channel through the needle for guiding the aspirated sample fluid. The needle channel opens at the needle tip. The housing includes a housing cavity and a housing channel opening into the housing cavity. The fitting includes a fitting cavity and a fitting channel. The fitting is configured for sealingly receiving the needle tip into the fitting cavity and for being inserted into the housing cavity, so that the fitting channel on one side fluidically couples to the needle channel and on another side couples to the housing channel.

    Abstract: A sample management device which comprises a source flow path in which a fluidic sample can flow, a volume flow adjustment unit configured to adjust a volume flow of the fluidic sample to be branched off from the source flow path at a fluidic coupling point, and a fluidic valve fluidically coupled with the source flow path and with the volume flow adjustment unit, wherein the fluidic valve is switchable into a branch off state in which the fluidic coupling point is established within the source flow path to branch off an adjustable volume of the fluidic sample from the source flow path via the fluidic coupling point while a flow of the fluidic sample in the source flow path continues.

    Abstract: A switching unit is configured for selectively fluidically coupling a sampling volume, a sampling drive, a mobile phase drive, and a separating device. In a sample load configuration, the switching unit is configured for fluidically coupling the sampling volume and the sampling drive, for moving the fluidic sample into the sampling volume. In a decouple configuration, the switching unit is configured for fluidically coupling the sampling volume between the sampling drive and the separating device, while the mobile phase drive is fluidically decoupled from the separating device. In a sample introduction configuration, the switching unit is configured for fluidically coupling the mobile phase drive, the sampling volume, and the separating device for introducing at least an amount of the fluidic sample stored in the sampling volume into the mobile phase for fluid separation by the separating device.
