Patent number: 9696261Abstract: A multi-channel device includes up to three channels for optical testing of liquid samples. The liquid sample(s) may include surface water, drinking water, processed water or the like. The multi-channel device may include a turbidity channel and a color channel that measure turbidity and color, respectively, of a liquid sample using spectrographic analysis. The multi-channel device may also include a colorimetric channel that measures the concentration of various analytes in a liquid sample, such as free chlorine, total chlorine, copper and phosphate.Type: GrantFiled: October 8, 2008Date of Patent: July 4, 2017Assignee: Ecolab USA Inc.Inventors: Eugene Tokhtuev, Christopher J. Owen, Viktor Slobodyan, William M. Christensen, Paul Schilling, Joseph Phillip Erickson

Patent number: 8084756Abstract: An ultraviolet (UV) fluorometric sensor measures a chemical concentration in a sample based on the measured fluorescence of the sample. The sensor includes a controller, at least one UV light source, and at least one UV detector. The sensor emits UV light in a wavelength range of 245-265 nm from the light source through the sample in an analytical area. The UV detector measures the fluorescence emission from the sample. The controller transforms output signals from the UV detector into fluorescence values or optical densities for one or more wavelengths in the wavelength range of 265-340 nm. The controller calculates the chemical concentration of the chemical in the sample based on the measured fluorescence emissions.Type: GrantFiled: July 1, 2011Date of Patent: December 27, 2011Assignee: Ecolab Inc.Inventors: Eugene Tokhtuev, Christopher J. Owen, Viktor Slobodyan, Anatoly Skirda, Paul Schilling, Anna Pilipchenko, Paul R. Kraus, Katherine M. Sanville, Joseph Phillip Erickson
