Deep-UV LED and laser induced fluorescence detection and monitoring of trace organics in potable liquids |
摘要 |
An apparatus for measuring fluorescence of potable liquids contained within an optical quartz cell includes a deep UV laser or a compact UV LED that generates a light beam. A UV blocking and visible light transmitting optical filter reduces out-of-band emission from the LED. The optical quartz cell is between a pair of plane mirrors so that light from the light source travels through it several times. A concave mirror collects a fluorescence signal and has a common optical axis with a lens. The common optical axis is normal to an optical axis of the light beam. The concave mirror and lenses are positioned on opposite sides of the optical quartz cell. A fluorescence detector is in optical alignment with the concave mirror and the lens. A boxcar averager is in electrical communication with the fluorescence detector. Optical wavelength selection of the fluorescence emission uses optical filters or a spectrometer.
