  • Temperature control of reaction vessel, system with reaction vessel, software product for system and use of system
    Patent number: 7754473
    Abstract: A method for rapid thermal control of a reaction volume from a preceding temperature to a target temperature includes first bringing at least the reaction vessel's second wall, which has high thermal conductivity, into direct contact with a first thermal block at a temperature higher than the target temperature if the target temperature is higher than the preceding temperature, or at a temperature lower than the target temperature if the target temperature is lower than the preceding temperature, until the reaction volume temperature is at least close to the target temperature; and then bringing the second wall into direct contact with a second thermal block at the target temperature. Also disclosed is a system (20) for detecting and/or quantitating a biological and/or chemical analyte in a sample and a software product for the system.

  • Detector for detecting photons or particles, method for fabricating the detector, and measuring method
    Patent number: 5914491
    Abstract: The object of the invention is a photon or particle detector which comprises a transmission dynode situated in a vacuum. The detector comprises a monolithically fabricated semiconductor structure in which electrons are arranged so as to travel from the semiconductor into a vacuum. At least a part of the multiplication region is formed into a layered structure incorporating at least one doped semiconductor transmission dynode and at least one vacuum space.

  • Photomultiplier used in liquid scintillation counting with specimen-encircling curved photocathode
    Patent number: 4687921
    Abstract: A photomultiplier used in liquid scintillation counting has an envelope, a base, an anode, a curved dynode structure and a photocathode. A specimen is inserted in a measuring area of the envelope for liquid scintillation counting. The photocathode has a concave surface, so that the specimen is encircled by the photocathode as completely as possible. The photocathode is positioned at a concave window of the envelope, so that a maximum number of photons directly impinge on the photocathode.
