  • Eliminating source lamp intensity drift effect using reference measurement between cuvettes
    Patent number: 11226346
    Abstract: A computer-implemented method for calibrating a photometer in an in-vitro diagnostics analyzer includes generating a cuvette map of a reaction ring identifying a plurality of cuvette locations. The cuvette map is used to identify a plurality of reference measurement areas between the plurality of cuvette locations. A plurality of reference measurements are acquired in the reference measurement areas using the photometer. The photometer is automatically calibrated based on a comparison of the reference measurements to a predetermined standard setup of the photometer.
    Type: Grant

  • Alignment system for cuvette segments on clinical chemistry instruments
    Patent number: 10545162
    Abstract: A method for aligning a reaction ring in an analyzer system using a gauge vertical reaction ring comprising at least one end slot includes inserting a light beam gauge into an aperture operable to hold the light beam gauge at a height corresponding to a photometer included in the analyzer system. The gauge vertical reaction ring is rotated on the reaction ring until the light beam gauge engages the end slot to confirm alignment of the reaction ring with the photometer.
