PURPOSE:To improve the accuracy with reduced errors by combining a linear approximation and a corve approximation to obtain a proximity in the reaction process of biological material. CONSTITUTION:Material in a measuring cuvette 4 is excited to emit fluorescence, which then, is separated into single colors with a spectroscope 8 passing a polarizing element 7 and reaches a photo detector 9. The polarizing element 7 is driven according to a command of a control section 12 and rotated repeatedly in an intermittent manner by 90 deg. at fixed time intervals. The emitted light of the material is separated into components orthogonal and parallel to the polarized excited light and enters a detector 9. It is converted into an electric signal and then into a digital signal with an analog-digital converter 11 which is memorized in a memory 15. Based on a light signal data of the vertical and parallel components memorized, an approximity equation is prepared with an arithmetric section 16. This is used to calculate the polarization intensity of the fluorescence in terms of the intended measuring time. |
