Patent number: 10107756Abstract: A method of fluorometrically detecting the concentration of chemical components in oxidizing formulations is disclosed. In a particular embodiment the detection is of the stabilizing component of picolinic acid, present in such formulations, although any component which fluoresces may be detected. According to the invention sample preparation of the oxidizing formulation includes adding to said sample an excess of reducing agent to bind peracid, and in the case of picolinic acid, adding to said sample an excess of terbium chloride. The sample then is subjected to radiation to induce fluorescence and the concentration of said chemical component is determined by a linear relationship between fluorescence emitted and the concentration of the target chemical.Type: GrantFiled: January 12, 2016Date of Patent: October 23, 2018Assignee: Ecolab USA Inc.Inventors: John Wilhelm Bolduc, Eugene Tokhtuev, Anatoly Skirda, Anna Pilipchenko, Justin Scott Valenstein, Amanda Bakken, Stacy Fawbush, Jeffrey S.

Publication number: 20160047746Abstract: A fluorometer for measuring fluorescence of a sample includes an excitation source for emitting electromagnetic radiation along a first beam path to induce fluorescence in the sample. An excitation filter transmits electromagnetic radiation from the excitation source toward the sample. An excitation filter holder supports the excitation filter and defines an aperture for passage of electromagnetic radiation from the excitation source. The aperture is positioned asymmetrically relative to the first beam path such that the aperture allows an asymmetrical portion of the electromagnetic radiation in the first beam path to pass toward the sample and the excitation filter holder blocks passage of a corresponding asymmetrical portion of the electromagnetic radiation in the first beam path.Type: ApplicationFiled: August 12, 2014Publication date: February 18, 2016Inventors: Eugene Tokhtuev, Anatoly Skirda, Anna Pilipchenko, John Wilhelm Bolduc, Justin Scott Valenstein

Patent number: 8980636Abstract: A system and method for performing automated titrations. An automatic titrator utilizes control devices and sensors adapted for various chemical reactions to perform titrations and determine the content of a desired component of a solution. Batch and continuous mode titrations are possible. Titrant is added to a sample either in varying amounts or rates and a titration endpoint is observed via sensors. Control devices detect when the titration endpoint occurs and calculates the desired content. Various reactions within the solution may be suppressed in order to titrate isolated components individually.Type: GrantFiled: March 15, 2013Date of Patent: March 17, 2015Assignee: Ecolab USA Inc.Inventors: John Wilhelm Bolduc, Blake Roberts Otting, Paul R.
