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.
