    Abstract: A detector arrangement for a blood culture bottle incorporating a colorimetric sensor which is subject to change of color due to change in pH or CO2 of a sample medium within the blood culture bottle. The detector arrangement includes a sensor LED illuminating the colorimetric sensor, a reference LED illuminating the colorimetric sensor, a control circuit for selectively and alternately activating the sensor LED and the reference LED, and a photodetector. The photodetector measures reflectance from the colorimetric sensor during the selective and alternating illumination of the colorimetric sensor with the sensor LED and the reference LED and generates intensity signals. The reference LED is selected to have a peak wavelength of illumination such that the intensity signals of the photodetector from illumination by the reference LED are not substantially affected by changes in the color of the colorimetric sensor.

    Abstract: To reduce measurement time, it may be considered to quicken reaction or speed up analytic determination. In existing analyzing devices, photometry is performed, typically, about every 15 seconds, so that it has not been possible to secure satisfactory reproducibility. Namely, reducing the measurement time and securing reproducibility have not been compatible. It has therefore been desired to increase the number of times of measurements performed in a short period of time. A cell disk is controlled to stop at a position for photometry during the time after a sample and a reagent are mixed and before measurement is finished and, while the cell disk is stopped, photometry is performed once or plural times thereby increasing the total number of times of measurements.
