  • Quantitative measurements of concentration and solubility using Raman spectroscopy
    Patent number: 7521254
    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.
    Type: Grant
    Filed: April 11, 2005
    Date of Patent: April 21, 2009
    Assignee: Transform Pharmaceuticals, Inc.
    Inventors: Wendy Pryce-Lewis, Evie Sun, Kentaro Shimizu
