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 degasser for degassing a mobile phase includes a degasser chamber with a degasser volume for receiving a degassing membrane, a delimiting unit for delimiting a first space of the degasser volume with respect to a second space of the degasser volume while maintaining a fluid connection between the first space and the second space. The first space in an operation in an environment of the degassing membrane includes a higher partial pressure of vapor of the mobile phase than the second space with a lower partial pressure of vapor of the mobile phase. The degasser further includes a suction unit for sucking a gas that passed through the degassing membrane from the second space, and/or an associated gas supply unit for supplying an associated gas in the second space or in a fluid conduit that is connected to the second space.

Abstract: A fluidic device includes a planar structure constituted by a plurality of laminated layers and accommodating a fluid channel extending up to a surface of the planar structure, and a female adapter piece configured for a fluid-tight accommodation of a male adapter piece having a fluid conduit. The the female adapter piece is connected or connectable with the planar structure so that, when the male adapter piece is accommodated in the female adapter piece, the fluid conduit is brought in fluid-tight fluid communication with the fluid channel. The fluid channel is exposed to the female adapter piece at a lateral surface of the planar structure at which the laminated layers are exposed.

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.
