ABSTRACT:
The present invention provides an apparatus and method for a noninvasive optical determination of the pH of a substance in a compartment in a closed system comprising a compartment wherein a substance resides which is permeable to at least one wavelength of light, a light source and light detecting device configured to obtain spectral data for a substance for at least one wavelength, a processor adapted to determine the pH of the substance by correlating the spectral data with predetermined spectral data for a known substance at a known pH at the at least one wavelength, and wherein the processor is further configured to control the release of the substance from the compartment to its end use.
