Abstract:
A pH-buffer measurement system that has at least one source for modifying the pH of a fluid entering the system, the source selected from an acid source and a base source. The acid source adds an acid equivalent to provide an acid reacted fluid and the base source adds a base equivalent to provide a base reacted fluid. The source is in fluid communication with a flow path and a component for determining a fluid characteristic of the acid reacted fluid or the base reacted fluid. The fluid characteristic that is measured is any one of a gas phase pressure, an electrical conductivity, or thermal conductivity.
