Abstract:
1. A system for determining a chemical species, and the concentrations of said chemical species, present in an electrically conductive liquid analyte whose electrical conductivity is measurable as a function of its temperature, said system comprising: at least one electrical conductivity sensor and at least one temperature sensor in contact with an analyte of interest, said sensors in communication with a data acquisition system that measures the electrical conductivity and temperature of said analyte at a plurality of temperatures; a temperature control device adapted to vary the temperature of said analyte of interest while the electrical conductivity thereof is being measured by said data acquisition system; a data acquisition system adapted to transfer measured electrical conductivity and temperature data from said data acquisition system to a microprocessor-based device; and a program that, in combination with said microprocessor-based device, is adapted to:
