Abstract: The present invention relates to an assembly comprising a source of electromagnetic radiation, a detector assembly comprising a detector for electromagnetic radiation, a tube assembly comprising a portion of a tube, and a source optical element configured to transmit electromagnetic radiation received at a receiving end to an emitting end of the source optical element. The detector assembly comprises a detector assembly receiving end positioned to receive at least a part of the electromagnetic radiation from the source, wherein at least part of the electromagnetic radiation received at the detector assembly receiving end is received by the detector.

Abstract: The present disclosure relates to an excitation device for exciting an oscillation, comprising a fixable portion, a movable portion configured to move with respect to the fixable portion, a connection portion, wherein the movable portion is connected to the fixable portion via the connection portion, a piezo element fixedly mounted to the fixable portion, and a connecting element mechanically connecting the piezo element and the movable portion. Furthermore, a Coriolis flow meter comprising a measuring tube, at least one sensor configured to detect motion of the measuring tube, and an excitation device configured to excite an oscillation of the measuring tube is disclosed.

Abstract: The present disclosure relates to a measuring tube for a Coriolis flow meter, comprising a looped tube section, and two connecting tube sections, wherein a first end of each of the two connecting tube sections is respectively fluidly connected to a different end of the looped tube section. Further, each of the connecting tube sections comprises a first portion and a second portion, wherein the looped tube section defines a first plane, wherein the second portion of each connecting tube section extends out of the first plane in a first direction, and wherein the first portion of each connecting tube section extends out of the first plane in a direction opposite to the first direction. Additionally the present disclosure relates to a Coriolis flow meter comprising a respective measuring tube.

Abstract: The present invention relates to a method of operating a pump generating a flow of a fluid with a pressure, the method comprising operating the pump with a pump speed S satisfying the equation S=Ssimple(1+COR(t)); wherein S is the pump speed, Ssimple is the pump speed disregarding any compression and/or expansion of the fluid, t is a time, and COR(t) is a time dependent correction function; wherein the time dependent correction function COR(t) is a product of a corrective amplitude Acor and a time-dependent function f(t), i.e., COR(t)=Acor·ƒ(t); and wherein the corrective amplitude Acor is set based on a measure for the flow and a measure for the pressure. The present invention also relates to a corresponding use, a pump, a pump system and an HPLC system.

Abstract: A fluidic plug unit for liquid-conducting components, in particular for high-performance liquid chromatography, includes a plug housing that has a plug region with a front plug region and a rear plug region which is adjoined thereto in an axial direction. The plug unit is designed for connection to a bushing unit. In a connected state of the plug unit and bushing unit, an annular space, which is substantially closed on all sides, is formed for a sealing element of the plug unit, the annular space being bounded by an outer wall of the front plug region and an inner wall of the receiving recess of the bushing unit.

Abstract: A switching valve, in particular for controlling a fluid subject to high pressure is described. The switching valve has at least one valve unit, which includes a valve seat element and a switching element guided movably in a guide element, wherein the valve seat element and the switching element interact to provide a switching valve function. The valve seat element and the guide element are provided in a housing. The valve seat element, the guide element and the housing form a through flow channel for the fluid to be controlled. An elastically and/or plastically deformable sealing body is provided in a fully enclosed space between the inner wall of the housing and the outer walls of the valve seat element and of the guide element. The sealing body can be subject to a predetermined pressure to seal off the through flow channel from the housing and subject the valve seat element and the guide element to an inward-directed preload.

Abstract: The invention relates to a fluidic plug unit for liquid-conducting components, in particular for high-performance liquid chromatography, with a plug housing that has a plug region with a front plug region and a rear plug region which is adjoined thereto in an axial direction. The rear plug region has a larger cross section than the front plug region. The plug unit is designed for connection to a bushing unit. In a connected state of the plug unit and bushing unit, an annular space, which is substantially closed on all sides, is formed for a sealing element of the plug unit, the annular space being bounded by an outer wall of the front plug region and an inner wall of the receiving recess of the bushing unit.
