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 using a multi-purpose reagent composition to simultaneously determine concentrations of at least two analytes in a water sample. In one embodiment, the multi-purpose reagent composition used is for simultaneously determining free chlorine concentration and pH and comprises a free chlorine sensitive dye and a pH indicator. In another embodiment, the reagent composition used is for simultaneously determining of free chlorine and anionic polymer and includes a free chlorine sensitive dye, a pH buffer, a cationic dye, and an organic co-solvent. Thus, the pairs of free chlorine and pH or free chlorine and anionic polymer are determined using a single reagent composition. The reagent composition can also be the main reagent for one analyte analysis when it is used alone and also function as an ancillary reagent when it is combined with a second reagent composition for the determination of another analyte.
