Abstract: An optical absorbance spectrometer includes a sample housing, a light source and a spectral sensor. The sample housing comprises at least two sample cells configured to hold a sample, respectively, and includes an optical waveguide which is configured to guide light from an input side, through the sample cells, to an output side. The light source is operable to emit broadband light and is connected to the input side to couple emitted light into the optical waveguide. The spectral sensor is connected to the output side and operable to receive light from the optical waveguide and to detect the intensity of the received light at multiple wavelengths.
