    Abstract: A procedure for photometric measurement of liquids in a reaction vessel in an automatic analyser, with a radiation flow having its course perpendicular to a row of the reaction vessel, so as to provide a reliable and positively operating measuring method for the photometric measurement of the liquids. The procedure is characterized in that the radiation flow and the reaction vessel are in movement relative to each other during the measurement. The invention affords the advantage of improved accuracy of measurement and improved reliability since it becomes possible, by measuring a moving object and at the same time calculating the mean of the radiant flux over accepted portions of the signal, to eliminate the error of measurement introduced by a dirt particle or by a scratch. The invention also concerns a row of reaction vessels employed in the procedure, wherein each reaction vessel is contiguous to the next and separated by a wall. The row of reaction vessels is characterized in that the bottom of each reaction vessel consists of a lens focussing luminescence radiation. This affords the advantage that the lens enables a luminiscence measurement to be performed simultaneously with the photometric measurement.

    Abstract: According to one embodiment, an automatic analyzer includes a magnetic field generator, a photometric unit, a measurement unit, and a decision unit. The magnetic field generator causes magnetic separation in a reaction liquid stored in a cuvette by magnetic particles. The photometric unit includes a light source unit configured to generate light, and a detection unit configured to detect the light generated by the light source unit and generate an output signal corresponding to the detected light. The measurement unit measures a measurement item based on the output signal. The decision unit decides the use range of the output signal to be used to measure the measurement item in accordance with spatial unevenness of the magnetic separation by the magnetic field generator.

    Abstract: A measuring device (10) and a measurement method measure a concentration of gaseous/aerosol components of a gas mixture. A reaction carrier (14) has a flow channel (42) defining a reaction chamber (46) having a optically detectable reaction material (48), that reacts with a gas mixture component or with a reaction product. The measuring device (12) includes a gas-conveying assembly (2) with a gas-conveying apparatus (28) conveying the gas mixture and a detection assembly (3), which has a lighting apparatus (37) for lighting the reaction chamber (46), an optical sensor (38) for sensing the optically detectable reaction, and an evaluating unit (4) evaluating sensor data and determining a concentration of the component of the gas mixture. The detection assembly (3) senses a speed of a reaction front (6) propagating in the flow direction in the reaction chamber (46) and determines a preliminary concentration from the speed of the reaction front (6).

    Abstract: A method, apparatus for executing the method, and computer program products for use in such an apparatus. The method includes scanning an interrogating light across multiple sites on an array package including an addressable array of multiple features of different moieties, which scanned sites include multiple array features. Signals from respective scanned sites emitted in response to the interrogating light are detected. The interrogating light power is altered for a first site on the array package during the array scan, based on location of the first site or on a determination that the emitted signal from the first site will be outside a predetermined value absent the altering (which allows for protecting a detector against expected overly bright sites), or is altered during the array scan based on the detected interrogating light power (which allows for compensating for light source drift during an array scan).
