Chromoionophore And Method Of Determining Potassium Ions

View page
US Patent:
7960181, Jun 14, 2011
Filed:
May 2, 2007
Appl. No.:
11/743569
Inventors:
Huarui He - Alpharetta GA, US
Chao Lin - Alpharetta GA, US
Neeta Raje - Alpharetta GA, US
Chuseng Liu - Atlanta GA, US
Assignee:
OPTI Medical Systems - Westbrook ME
International Classification:
C07D 245/00
C07D 245/04
C07D 245/06
C07D 487/00
US Classification:
436166, 540470, 540471
Abstract:
The invention relates to methods of determining potassium ions in a sample, wherein the ions are contacted with a compound having chromophoric moiety and an ionophoric moiety, where the ionophoric moiety interacts with the potassium ions present in the sample, resulting in the chromophoric moiety changing its radiation absorption properties in the ultraviolet and visible regions of the spectrum. For example, a change in an intensity of an absorption maximum is measured and the ion concentration is determined accordingly.
