Ternary solution e.g. water-ethanol-glucose concentration determining method for e.g. food industry, involves calculating concentration of original solution from measured capacity or impedance based on empirical mathematical model

摘要

The method involves measuring capacity or impedance of original 3-component solution e.g. water-ethanol-glucose solution, and a sample of the solution. The solution is provided in a chamber, and the sample is selectively changed by reverse osmosis by using a reverse osmosis module or reverse osmosis membrane. Concentration of the original solution is calculated from the measured capacity or impedance based on an empirical mathematical model.
