A chemical reactor is implemented on a substrate. The chemical reactor has multiple ducts for transporting a fluid and/or gas during use of the chemical reactor, in which the ducts optionally include pillar structures and at least one connection duct connected between two of the multiple ducts for transporting the fluid and/or gas from one duct to another. In the connection duct, a series of individual pillar structures are positioned behind each other in the longitudinal direction of the connection duct.

The present disclosure relates to methodologies, systems, and apparatus for controlling fluid flow within a chromatography system. The chromatography system includes a mobile phase pump configured to pump a liquid mobile phase through a column and a restrictor positioned downstream of the column and upstream of a detector. The system also includes a valve configured to operate in at least two positions. In a first position, the valve is configured to direct the output of the column to bypass the valve and reach the detector, while in the second position the valve directs the output of the column to waste.

The present invention describes a device for distributing incoming fluid or for collecting fluid being discharged from a column forming part of an assembly of N columns in series intended to be used in a simulated moving bed separation process. The present device can be used to very substantially reduce the non-selective volumes at each column, while at the same time providing the flow with good synchronicity.

Aspects of the present disclosure include branching fluid passages in an apparatus that reduce turbulent flow and generate evenly distributed fluid pressure as the fluids branch off into the different passages. In some embodiments, the branching passages may be subdivided into two sets: the branching passages for the liquid fuel and the branching passages for the liquid oxidizer. In some embodiments, the two sets of passages are carefully designed in an elegant yet extremely intricate manner that is optimized for proper fluid flow and maximal burn efficiency. The ends of all of the passages meet at the injector interface, which dispense the liquids into the combustion chamber for ignition. Generally, these designs are achieved through additive manufacturing, and would be extremely difficult, if not impossible, to be manufactured using traditional techniques.

An apparatus for reaction chromatography comprising: a chromatography column, the column having a fluid outlet for an eluate flow, wherein the fluid outlet is configured with two or more fluid ports, the two or more fluid ports comprising one or more reactant ports, wherein each reactant port is for connecting a reactant flow into the eluate flow to react with the eluate flow, and one or more product ports for receiving the reacted eluate flow; one or more reactant sources in fluid communication with the one or more reactant ports to provide the reactant flow; and one or more processing units in fluid communication with the one or more product ports to process the reacted eluate flow.

An arrangement for a column comprising a stand provided with a platform adapted to receive a second end of a tubular housing and for supporting the arrangement on a floor, a first end unit removably connected to a first end of the tubular housing, an adaptor assembly movable within said tubular housing and an adaptor rod connected to said adaptor assembly, which adaptor rod is arranged to extend through an opening in the first end unit. A frame is connected to the first end unit, which frame and first end unit can be lifted and lowered in a substantially vertical direction, so that the tubular housing may be removed and substituted for another tubular housing with different dimensions in relation to the removed tubular housing when the frame and first end unit are lifted.
