    Abstract: A fluid pump for a fluid separation device for separating a fluid includes a fluid inlet being supplyable with fluid at an inlet pressure (pI), and a fluid conducting mechanism configured for conducting the fluid supplied to the fluid inlet towards a connected fluidic path, in which the fluid conducting mechanism is controllable so that, regardless of a value of the inlet pressure (pI), the fluid is continuously conducted away from the fluid inlet with a definable flow rate (FT).

    Abstract: A supply flow path for supplying a solvent is described. The supply flow path includes metering devices each with a piston, the metering devices being adapted for metering the solvent through separate source paths feeding the supply flow path. The supply flow path further includes a control unit adapted for controlling the metering devices' piston movement in accordance with solvent pressure, wherein a variation of the solvent pressure gives rise to a corresponding variation of a solvent volume contained in the supply flow path or a part thereof. The control unit is adapted for compensating for the variation of the solvent volume by corresponding movements or forward or backward displacements of the pistons.

    Abstract: A method for controlling movement of a piston in a metering device is described. The method comprises supplying a fluid by actuating the metering device's piston, wherein compression or expansion of the fluid causes corresponding temperature variations. The method further comprises superposing a corrective movement onto the piston movement, with the corrective movement at least partly compensating for at least one of thermal expansion and contraction of the fluid induced by the temperature variations. In one embodiment, the corrective movement imposed onto the piston movement comprises two components: a reduction (74) of the compression jump (73), and a subsequent increase (75) of the piston's forward displacement rate (71) during a period (76) of time (72).

    Abstract: A sample injector for a liquid analysis device includes a multi-route switching valve and a sample conduit. The valve alternatively connects a solvent pump directly to a chromatographic column or via a sample conduit. The sample injector further has a flush solvent delivery device. The flush solvent delivery device delivers at least one flush solvent to the sample conduit of the sample injector. The sample injector also has a sample intake device. The sample intake device provides liquid sample to the sample conduit.
