CPC classification number: G01N21/0303 , G01J3/20 , G01J3/42 , G01N21/031 , G01N21/05 , G01N21/31 , G01N21/33 , G01N2021/3129 , G01N2021/3133 , G01N2021/3137 , G01N2021/3155 , G01N2021/3185
Abstract: A spectrometer or multiple wavelength absorbance detection method and apparatus providing improved accuracy for an array of measurements at different wavelengths. The spectrometer utilizes a multiple wavelength illumination system with an array of independent detectors with different pathlength cells, where each cell is illuminated with predominately monochromatic light after separation by a light dispersing element. Each sample cell has an optical pathlength, optics and photodetection device that are optimized for its particular wavelength to accurately measure absorbance through an expected substance.
