Abstract
The present invention provides methods which allows for the determination of concentration or solubility in a multi-component system using Raman spectroscopy. The present invention circumvents the necessity of constructing a calibration curve in order to analytically determine the concentration/solubility of a solute in a homogeneous liquid or a homogeneous solid. Methods of determining the saturation concentration of a solute in a polymer matrix or a polymer matrix film are also provided.
