Voltage characteristic comparator for discriminating solutions

摘要

An apparatus and method for rapidly identifying the chemical compositions and concentrations of solutions and for discriminating among solutions of different chemical compositions and concentrations of the solution is monitored by applying across a predetermined volume of the solution a predetermined voltage for a predetermined time after which the application of voltage is terminated and the voltage time characteristic measured across the solution as the voltage decays is compared with an empirically obtained voltage versus time characteristic for a solution having a standardized composition and/or concentration.
