ANALYTE ION DETECTION METHOD AND DEVICE

摘要

The present invention relates to 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/or 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; compensating for said ion interference and/or 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.
