US Patent:

7736900, Jun 15, 2010

Filed:

Feb 5, 2002

Appl. No.:

10/467181

Inventors:

Adam T. Pauli - Cheyenne WY, US
Raymond E. Robertson - Laramie WY, US
Jan F. Branthaver - Chatham IL, US
John F. Schabron - Laramie WY, US

Assignee:

University of Wyoming Research Corporation - Laramie WY

International Classification:

G01N 33/24

US Classification:

436 29, 436163, 436164

Abstract:

A system for determining parameters and compatibility of a substance such as an asphalt or other petroleum substance uses titration to highly accurately determine one or more flocculation occurrences and is especially applicable to the determination or use of Heithaus parameters and optimal mixing of various asphalt stocks. In a preferred embodiment, automated titration in an oxygen gas exclusive system and further using spectrophotometric analysis (2-8) of solution turbidity is presented. A reversible titration technique enabling in-situ titration measurement of various solution concentrations is also presented.
