On an analytical device for photometric detection of chemistry and/or fluid samples comprising a rotatable disc like body (1) a plurality of receptables (7) for fluid samples and optical means (9) for guiding light beams through the receptables are arranged. At least part of the optical means (9) are designed and/or arranged such, that at least part of the light beams is deflected and guided through the receptables in an angle to the radially outward direction on the disc like body (1) which means in an angle to the radius, connecting the respective optical means with the rotation axis (9) of the disc like body (1).
摘要:
Apparatus for retaining magnetic particles within a segment of a flow-through cell during flow of a fluid through the cell. The apparatus comprises (a) an electrical current source; (b) an electromagnet (121, 122) having a winding (122) connected to the current source and a gap between at least one pair of poles (107, 108) each of which has a corrugated outer surface and (c) a microchannel (102) used as flow-through cell. The microchannel (102) is configured and dimensioned to receive an amount of magnetic particles to be retained within it and to allow flow of a liquid therethrough. The liquid carries molecules or particles to be captured by means of the magnetic particles. A portion of the microchannel (102) is inserted in the gap.
