Abstract:
1. A method for reducing measurement error in concentration analysis of electrolytic solution, comprising: (a) establishing an initial model for determining concentration Y of a component of interest in electrolytic solution based on a measurable parameter X that is correlative to Y, wherein correlation between X and Y in said initial model is expressed as Y=ƒ(X); (b) providing a standard electrolytic solution that contains said component of interest at a known concentration Y (c) calculating a theoretical parameter value X (d) measuring the actual parameter value X (e) determining an adjustment factor e, wherein e=X (f) constructing a revised model that provides Y=ƒ(X+e) for future concentration determination of the component of interest; and (g) optionally, repeating steps (b)–(f) for model revision on a periodical or threshold basis.
