Abstract: A method of normalizing an analyzer response value of a fluorescence analyzer is provided. The method includes measuring an excitation spectrum of the analyzer and measuring an emission sensitivity spectrum of the analyzer. Next, a normalization factor based at least in part upon the excitation spectrum of the analyzer and the emission sensitivity spectrum of the analyzer is determined. The sample is then analyzed to obtain an uncorrected analyzer response value. A normalized analyzer response value is calculated based at least in part upon the uncorrected analyzer response value and the normalization factor.

Abstract: A fiber optic fluid opacity sensor includes a light source (12) transmitting light to dividing means (14) for providing a sample light signal (18) and a reference light signal (20) to dual photodetectors (26, 28). Sample and reference optical pathways (19, 21) are defined by optical fibers (18, 20) spaced apart from and axially aligned with the photodetectors (26, 28) at a predetermined distance. Signal processing means (30) takes the log ratio output of the signals from the photodetectors (26, 28) for cancelling the effect of light source drift since the same source (12) is common to both for measuring the light transmission and determining opacity therefrom. A sample probe (40) contains the photodetectors (26, 28) and the sample and reference optical pathways (19, 21). The light source (12) and the signal processing means (30) are situated outside of the probe (40) and by virtue thereof outside of the sample process line (48).

Abstract: According to one embodiment, an automatic analyzer comprises a light source, a spectroscope, a photo detection unit, a storage unit, a selection unit, and a calculation unit. The storage unit stores photo detector identifiers related to photo detectors and wavelength band identifiers in association with each other. The selection unit selects a specific photo detector from photo detectors. The specific photo detector corresponds to a specific photo detector identifier associated with a wavelength band identifier of a wavelength band according to a measurement item of a sample. The calculation unit calculates an absorbance related to the measurement item based on a signal from the selected specific photo detector.

Abstract: A device implements a method for detecting contamination of an FTIR-based panel. The apparatus generates projection signals representing detection lines that have propagated on a plurality of propagation paths by total internal reflection (TIR) inside a transmissive panel such that contamination on the panel surface causes attenuation (frustration) of at least one of the projection signals. The device generates a transmission value for each detection line in the transmissive panel, and determines the presence of contamination on the surface of the panel by comparing the transmission values according to at least one of the presented comparison techniques.
