May 19, 2005 Quad-channel filter fluorometer gathers data for atmospheric photochemistry to determine effects of pollution on climate and air quality. It uses line emission light sources and band filters for discrete wavelength excitation and is compatible with 6–24 µL HPLC flow cells. Configurable for series or parallel detection, unit employs 4 photomultiplier detectors and provides consolidated control of output amplifier time constant and photomultiplier voltage.
