Visual, Continuous And Simultaneous Measurement Of Solution Ammonia And Hydrogen Ion Concentration

View page
US Patent:
8202503, Jun 19, 2012
Filed:
Aug 27, 2010
Appl. No.:
12/870004
Inventors:
David L. Putnam - Sammamish WA, US
Janice A. Sharick - Sammamish WA, US
Jason A. Putnam - Sammamish WA, US
Assignee:
Photonic BioSystems, Inc. - Sammamish WA
International Classification:
C01C 1/00
US Classification:
423352, 423237
Abstract:
Particular aspects provide novel devices and methods for accurately measuring total ammonia (NHplus NH) in a solution (e. g. , freshwater and saltwater) by spatially proximate, simultaneous and continuous quantitative measurement of solution pH and ammonia. The devices overcome prior art inaccuracies relating to non-homogeneous sampling, and to spatial, temporal and thermal sampling discontinuities. Particular embodiments provide a combination pH and ammonia measuring device, comprising: a submersible member; a submersible non-bleeding ammonia-sensing portion attached to the submersible member and suitable to provide for a continuous visual indicator of solution ammonia concentration; a submersible non-bleeding pH-sensing portion attached to the submersible member and suitable to provide for a continuous visual indicator of solution pH; visual ammonia and pH indicator comparison means suitable for comparative quantitative determination of solution ammonia concentration and pH. Additional aspects provide novel ultra-sensitive devices and methods using same for measuring ammonia in air or solution.
