摘要： Systems and methods are described for measuring pH of low alkalinity samples. The present invention provides a sensor array comprising a plurality of pH indicators, each indicator having a different indicator concentration. A calibration function is generated by applying the sensor array to a sample solution having a known pH such that pH responses from each indicator are simultaneously recorded versus indicator concentration for each indicator. Once calibrated, the sensor array is applied to low alkalinity samples having unknown pH. Results from each pH indicator are then compared to the calibration function, and fitting functions are extrapolated to obtain the actual pH of the low alkalinity sample.

摘要： The concentration of an anionically charged polymer in an aqueous solution is determined with a thin solid film having a polymer matrix and a cationic dye. A sample of an aqueous solution containing at least one anionically charged polymer to be tested is applied to the film sensor. The absorbance of the film sensor is measured after the sample has been applied. The absorbance of the film sensor is then compared with a calibration curve of the absorbance of samples containing known concentrations of the anionically charged polymers to determine the concentration of anionically charged polymer in the sample.

摘要： A method of quantitatively measuring the concentration of a chemical species in a sample solution with a sensor film. A hydrogel sensor film is prepared having a chemical composition comprising an indicator that changes its optical property in the ultra-violet, visible or near-infrared spectral range upon being exposed to the chemical species in the sample solution. The film is exposed to a fixed amount of the sample solution. The concentration of the chemical species in the sample solution is quantified using the average absorbance measured from the sensor film.
