摘要:
The present invention provides a system for the production of a radiopharmaceutical including a radiosynthesis apparatus and a disposable cassette. The system of the invention includes a device that enables a position on the cassette to be freed for inclusion of an additional reagent vial. With the system of the invention a broader range of radiochemical syntheses can be envisaged using the cassette.
摘要:
A microchannel apparatus comprising a conduit including a microchannel mixing section, a microchannel reaction section, a microchannel heat transfer section, and a separation section, where the microchannel mixing section includes direct injection inlets, where the microchannel mixing section is downstream from the reaction section, and where the separation section is downstream from the reaction section. Further exemplary embodiments are also disclosed.

Means for enabling plating on sites of complex configuration, etching for fine complex pattern, etc. through reduction of the viscosity resistance brought about by walls of fine liquid channel of microreactor. In particular, a microreactor comprising a liquid inlet, a fine liquid channel and a liquid discharge zone characterized in that the liquid channel is formed of a magnetic barrier of band ferromagnet so that a magnetic liquid introduced through the inlet undergoes at least one operation of chemical reaction, mixing, extraction and absorption in the liquid channel. Further, there is provided means for plating or etching performed by causing a plating solution or an etching solution to flow through the liquid channel.

Microfluidic fraction collectors fractionating a sample stream into discrete sample volumes are provided. Fluid flow control mechanisms divert selected portions of a sample stream from an inlet channel into one or more branch channels. The fluid flow control mechanisms may be passive, relying on sample volume and fluidic impedance to establish the sample collection sequence. Alternatively, active fluid flow control mechanisms may be controlled, with or without feedback, to establish the sample collection sequence.

An apparatus includes a substrate having a recess and a multitude of particles arranged in the recess. A first portion of the particles is joined to a porous structure by means of a coating. A second portion of the particles is not joined by means of the coating. The first portion of the particles is arranged closer to an opening of the recess than the second portion of the particles so that a leaking of the second portion of the particles from the recess through the opening is prevented.

The present invention provides a supporting unit of microfluid system having a smaller restriction on the number of the steps and capacity of the reaction and analysis that can be produced easily, and a microfluid-system supporting unit allowing mounting of complicated fluid circuits densely. The present invention relates to a microfluid-system supporting unit, comprising a first supporting plate and at least one hollow filament constituting the channel of the microfluid system, wherein the hollow filament is placed on the first supporting plate in any shape and a particular internal region of the hollow filament has a function.
摘要:
This invention relates to a process for converting a carbonaceous material to a desired product comprising methane, methanol and/or dimethyl ether, the process comprising: gasifying the carbonaceous material at a temperature in excess of about 700° C. to form synthesis gas; and flowing the synthesis gas through two or more reaction zones in a microchannel reactor to convert the synthesis gas to the desired product.

The disclosed invention relates to a process and apparatus for separating a first fluid from a fluid mixture comprising the first fluid. The process comprises: (A) flowing the fluid mixture into a microchannel separator in contact with a sorption medium, the fluid mixture being maintained in the microchannel separator until at least part of the first fluid is sorbed by the sorption medium, removing non-sorbed parts of the fluid mixture from the microchannel separator; and (B) desorbing first fluid from the sorption medium and removing desorbed first fluid from the microchannel separator. The process and apparatus are suitable for separating nitrogen or methane from a fluid mixture comprising nitrogen and methane. The process and apparatus may be used for rejecting nitrogen in the upgrading of sub-quality methane.
