Claim One:
1. A method of assessing concentration of at least one analyte ion in a liquid, the method including: contacting the liquid with a plurality of electrodes, each of which is configured to generate a signal in response to sensing a selected ion in the liquid; receiving the signal from each of the electrodes; processing the signal from each of the electrodes using a neural network algorithm residing on a processor that has been trained to calculate ion interference between the selected ion and other ions in the liquid sensed at one of the electrodes and electrode interference between ones of the electrodes sensing a same selected ion based on a result of a comparison of training data indicative of a known ionic concentration applied to the neural network algorithm and the known ionic concentration; processing data of the signal from one or more of the electrodes with a genetic Independent Component Analysis (geneticICA) algorithm into Independent Components (ICs) and providing the ICs as input data for the neural network algorithm, wherein the geneticICA algorithm is based on a genetic algorithm using a number of random points in a Probability Distribution Function (PDF) of the data; compensating said ion interference and for said electrode interference; and assessing the concentration of the at least analyte ion in the liquid on the basis of a compensated output from the neural network algorithm.
