摘要:
The invention relates to a micro-fluidic system consisting of modules (1) that are arranged side by side in a row, each module containing a micro-fluidic unit (6) and an associated electric control unit (15). According to the invention, the rear faces (3) of the modules (1) lie against a common vertical rear wall unit (2) and are held against said unit. In the modules (1), the respective control unit (15) is located in the vicinity of the rear face (3) and the micro-fluidic unit (6) is situated in a region that is remote from said rear face (3). The control units (15) can be connected to an electric line bus (20) that runs through the rear wall unit (2) via electric connectors (26, 27) that are located on the rear faces (3) of the modules (1) and on the rear wall unit (2) and the micro-fluidic units (6) of two respective neighbouring modules (1) are interconnected to allow the passage of fluid via a connecting part (11) that contains connection channels and that spans the relevant modules (1, 4).

摘要:
A modular fluid processing architecture (10) is provided that consists of a matrix of nested tubes or processor modules (11A-D) secured between end block manifolds (12 & 13). Multiple chemical reactors may be housed in the annular spaces formed by the nesting of the tubes, and the processes may be integrated through flow splitting, mixing, switching and heat exchange in the manifolds. A flow switching system (5-9) may provide the ability to switch the flows on or off in individual processors or in banks of such processors. The switching may effect the operation of some or all of the processes. Such switching can facilitate rapid and close following of demand for the processor output while allowing each processor to run within a range of high efficiency, since processors may be turned off or on in response to falling or rising demand for the output.
摘要:
A method of optimising a reaction in a microreactor. Two reaction fluids A,B as supplied to a microchannel 6 and their relative proportions are varied in a controlled manner. A sensor 13 monitors a reaction characteristic and determines the relative proportion of the fluids which optimises the yield of the reaction product. The total flow rate can also be varied at the optimum relative proportion in order to determine the maximum overall flow rate at which completion of the reactions still occurs.

摘要:
A microreactor with a sensor 9, 11 in a reaction channel 6. The sensor comprises a pair of spaced apart electrodes through which an AC voltage is passed. The amplitude and phase of the current flowing between the electrodes is monitored allowing the impedance of the reaction fluid between the electrodes to be measured.

The invention relates to a system for carrying out the automated processing of fluids comprising combinable and interchangeable process modules (38, 39, 40), which each contain a control unit (6) and a fluid unit (7) that can be controlled by said control unit in order to execute a module-specific process function. The control units (6) are interconnected via a data bus (10), which is shared by process modules (38, 39, 40), and the fluid units (7) are interconnected via a fluid bus (44) comprising a number of channels (45). The configuration of at least one portion of the channels (45) of the fluid buses (44) can be varied in the areas of its connection to the fluid units (7) by using configuration devices, which can be provided in the form of adapters (41, 42, 43) located between the process modules (38, 39, 40) and the fluid bus (44).
