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.

1,017,188. Analysing fluids electrically. ESSO RESEARCH & ENGINEERING CO. April 14, 1964 [May 14, 1963], No. 15422/64. Heading G1N. Apparatus for determining the concentration of water vapour in a gas mixture comprises two similar piezo-electric crystals 10,11 (Fig. 3), each coated with a substrate 10a, 11a capable of absorbing the water vapour to change the resonant frequency of the crystal by an amount indicative of the concentration. The crystals are fed periodically with alternate dry gas and test gas mixture, and the difference in resonant frequencies is determined by a mixer 14, to be indicated on a recorder 17. The alternations of dry gas and test gas, produced by a rotating four-way valve 20, eliminate hysteresis effects produced by a direct difference measurement. Different substrates are given for water vapour and for other gases, to be deposited on a magnetostrictive or piezo-electric material.

A part of pre-treated water flowing into an ultraviolet irradiation tank is guided to a fluorometer. The fluorometer scans an excitation spectrum peak wavelength of the pre-treated water at a fluorescence wavelength fixed to 425 nm to obtain an excitation spectrum, and continuously measures an excitation peak wavelength thereof. Based on the analysis result obtained by the fluorometer, an ultraviolet irradiation device calculates an ultraviolet irradiation level target value for optimizing an ultraviolet irradiation level, and thus controls the irradiation level of ultraviolet rays emitted therefrom.

Total analysis systems and methods for simultaneously monitoring a suite of biological and/or chemical species in water and/or other process systems are disclosed. The system provides a sample-volume controlled sensor array comprising a fluid delivery device and a plurality of optical sensor elements for determining the presence and total concentrations of multiple analytes in the process system simultaneously. Image identification algorithms are provided for identifying the analytes based on image intensity, color pattern, positional arrangement, and the like. The methods incorporate multivariate optimization algorithms to analyze multiple sensor responses. This produces analytical results that are typically difficult to obtain without full system or variable compensation. The improved array response may then be utilized to measure, monitor, and control the concentration of analytes in the chemical or biological sample or water system.
