 Method/Apparatus/Procedure:
   The solubility values were calculated from the particle size growth in emulsions due to Ostwald ripening. The particle size analysis of emulsions was accomplished through the use of a photon correlation spectrometer. The  kinetics of particle size growth were observed until a 200 nm diameter was attained. The solubility measurement method showed a very low detection limit. Further details on Ostwald ripening kinetics are described elsewhere.1
