Abstract:
The invention relates to a biological analysis device (100) for measuring photoluminescence in a fluid present in a measurement cell (111). This device (100) comprises at least two light sources (121, 131) capable of emitting in different spectral ranges, suitable for carrying out absorption and fluorescence measurements respectively, and a detection device (140) comprising a detector (141), an optical system (142) and filtering means (144), these three latter components being mutually designed, according to the invention, to allow the measurement of absorption and/or fluorescence signals. According to the invention, the detector (141) can also be in an internal-gain configuration so as to allow fluorescence measurements and absorption measurements to be carried out sequentially.
Abstract:
An automatic analyzer for analyzing luminescence of a sample, comprises a photomultiplier (PMT) detector, sensitivity control means for controlling the sensitivity of the detector, memory means for preliminarily storing plural sensitivity control values for the sensitivity control means, and switching means for choosing one of me plural sensitivity control values depending on an object of measurement, such as a concentration range of a measurement item.
Abstract:
A photo-detector 122 generated signal 125 is measured as a sample set 192 comprising a long signal and a short signal. The short signal is scaled to the value of the long signal if the long signal exceeds a dynamic range 131 associated with the photo detector 122. In one embodiment, the short signal is obtained during a short time interval that is at the approximate middle of a long time interval such that the short and long intervals share a common median time value 194. Given such symmetry, an approximately linear signal 190 yields a proportionality parameter between the long and short signals thereby allowing the short signal to be scaled. The proportionality parameter facilitates determination of an integration independent component of the photo detector signal that should be removed from the measured long and short signals before scaling. A plurality of sample sets 260 can also be processed such that each sample set overlaps with its neighboring sample set, thereby increasing the effective number of sample sets.
