    摘要: The invention relates to a detector arrangement in an instrument for analysis of discrete liquid sample volumes in the microliter and/or nanoliter range contained in microchannel structures that are present in a disc shaped microfluidic device. The suggested detector arrangement comprises a detector head, supported to be driven and controlled for linear displacement and positioning in a first radial plane through a central axis of an associated rotary drive. A rotary member is carried for rotation about said central axis in a second radial plane in parallelism with said first radial plane. A vacuum source is connected with the rotary member and in air flow communication with a planar top surface of the rotary member for a wide area distribution of sub-pressure over said top surface, the rotary member carrying the disc shaped substrate in adhering contact with the top surface for spinning the substrate in equidistant and equiangular relation to the detector head.

    摘要: Method of manufacturing a microscale nozzle, comprising the steps of forming a microscale channel in the top surface of a substrate, said microscale channel comprising an inlet end and a nozzle-end, depositing a nozzle-forming layer in a section of the microscale channel, and removing material from the substrate at the nozzle-end of the microscale channel to expose at least a portion of said nozzle-forming layer. The manufactured microscale nozzle may be used for transferring a liquid sample form a microchip fluidic system into an external analytical device.

    摘要: A centrifugal-based microfluidic device (1) that comprises a hydrophilic microchannel structure (2) in which there is a A) a separation microcavity I (4) that comprises i) a liquid inlet I (5), and ii) a liquid outlet I (6) that is at a level below the level of liquid inlet I (5) and above the level of the bottom (8) of the microcavity (4) thereby defining a lower part (4b) and an upper part (4a) of the microcavity (4), and B) a microconduit I (17) that has an inlet end I (16) directly connected to liquid outlet I (6), and an outlet end I (18) that is at a lower level than inlet end I (6). A capillary valve I (24) is associated with microconduit I (17). The flow direction through liquid outlet I (6) is directed upwards and/or liquid outlet I (6) is placed in a downwardly turned part of an inner wall of the separation microcavity (4), and/or the part of microconduit I (17) next to liquid outlet I (6) is directed upwards.
