摘要： A method of assessing concentration of analyte ion(s) in a liquid can include 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. The signal received from each of the electrodes can be processed using a neural network algorithm trained to calculate ion interference between the selected ion and other ions in the liquid sensed at one of the electrodes and/or electrode interference between ones of the electrodes sensing a same selected ion based on a result of a comparison of training data. The ion interference and/or electrode interference can be compensated for, and the concentration of the analyte ion(s) in the liquid can be assessed on the basis of a compensated output from the neural network algorithm.
