An apparatus (30) which determines concentrations of each of three components that are intermixed in a homogeneous solution (34). Each component is detectable by at least one characteristic and more than one characteristic is associated with more than one component. First, characteristics that are quantitatively detectable in relation to the concentrations of the components are identified. A mathematical relationship is then developed between the components and the detectable characteristics using the detectable characteristics as independent variables. A sample of the solution is then analyzed to obtain quantitative data of each of the characteristics. The obtained quantitative data is …

Why it's free to use
- Filed April 29, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 29, 2011.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
