Abstract:
Disclosed is a sample dispatcher configured for individually introducing a plurality of portions of one or more sample fluids into a flow of a mobile phase of a separation system configured for separating compounds of the sample fluids. The separation system comprises a mobile phase drive configured for driving the mobile phase through a separation unit configured for separating compounds of the sample fluids in the mobile phase. The sample dispatcher comprises a plurality of sample reservoirs, each configured for receiving and temporarily storing a respective sample fluid portion or at least a part thereof. The sample dispatcher is configured for selectively coupling one of the plurality of sample reservoirs between the mobile phase drive and the separation unit, and further for coupling at least two of the plurality of sample reservoirs in parallel between the mobile phase drive and the separation unit.
Abstract:
A valve arrangement includes a valve module and a base module. The valve module includes a stator and a rotor, which is rotatable relative to the stator such that at least one fluid connection is formable between the stator and the rotor. The base module includes at least a part of a force control mechanism for selectively implementing a force-releasing or force-coupling of the rotor and the stator, whereby the valve module and the base module are selectively coupleable to or decoupleable from each other.
Abstract:
A mixer for mixing a mobile phase in a sample separation device for separating a fluidic sample, wherein the mixer includes a fluid inlet for supplying the mobile phase to be mixed to a mixing volume, a movable body configured for rotating and axially moving in the mixing volume to thereby mix the mobile phase, and a fluid outlet for supplying the mixed mobile phase to a mobile phase consumer.
Abstract:
A fluidic device (200), comprising a planar structure (202) constituted by a plurality of laminated layers (212) and accommodating a fluid channel (204) extending up to a surface of the planar structure (202), and a female adapter piece (206) configured for a fluid-tight accommodation of a male adapter piece (208) having a fluid conduit (210), wherein the female adapter piece (206) is connected or connectable with the planar structure (202) so that, when the male adapter piece (208) is accommodated in the female adapter piece (206), the fluid conduit (210) is brought in fluid-tight fluid communication with the fluid channel (204), wherein the fluid channel (204) is exposed to the female adapter piece (206) at a lateral surface of the planar structure (202) at which the laminated layers (212) are exposed.
Abstract:
A fluid supply device for providing a mobile phase for a sample separating device includes a supply path configured to provide a fluid for forming at least a part of the mobile phase, a fluid conveying unit configured to receive and pressurize the fluid from the supply path and to convey the fluid to the sample separating device, and a sterile filter disposed in the supply path upstream of the fluid conveying unit and configured to filter the fluid. The fluid supply device may include a pre-filter pump configured to push the fluid through the sterile filter and/or a buffer unit configured to buffer the fluid.
Abstract:
A fluidic valve for switching between different fluid coupling states includes a stator having at least one fluidic stator interface, a rotor having at least one fluidic rotor interface, wherein the rotor is rotatable relative to the stator to thereby switch the fluidic valve between a plurality of different fluid coupling states between the at least one fluidic stator interface and the at least one fluidic rotor interface, and a force transmission mechanism configured for pressing the stator and the rotor together by a contactless force transmission to provide for a fluid tight sealing between the stator and the rotor.
