    摘要: In a system for operation or handling of a laboratory microchip (41) for chemical processing or analysis, the microchip (41) is mounted in a first physical unit (42). The microchip (41) is arranged on a mounting plate, such that it is readily accessible from the top and thus the fitting and removal of the microchip is considerably simplified. Furthermore, the first physical unit (42) comprises an optical device (43) for contactless detection of the results of the chemical processes conducted on the microchip. The supply systems necessary for the operation of the microchip are arranged in a module unit that has a separable connection with a second physical unit. The proposed modular layout enables ease of interchangeability of the required supply systems and thus, overall, ease of adaptability of the proposed system for various types of microchips.

    摘要: A contactless detection cell (1) for detecting an electrical property of one or more sample compounds in a flow path is described. The contactless detection cell (1) comprises a transmitter electrode (3) adapted for capacitively coupling an AC current into a detection channel (4) of the flow path, and a receiver electrode (5) adapted for receiving the AC current that has been coupled into the detection channel (4). An inner cross-section (IDDET) in at least a section of the detection channel is different than an inner cross-section (IDSEP) of the flow path (2) towards the detection channel (4).
