    摘要: The present invention provides a reference electrode solution containing ammonium salts and phosphonium salts for the potentiometric measurement of pH and method of using the same. The use of the ammonium salts and the phosphonium salts to replace potassium chloride or sodium chloride as reference electrolytes in a standard reference electrode minimizes the formation of precipitates in sample solutions containing cation-sensitive compounds. Disruption of ion flow through the reference electrode is eliminated, and accurate pH measurements may be obtained in solutions that contain compounds having a strong affinity for hard cations.

    摘要: The present invention relates to a dispersion of an active agent, which includes a multiphase system of an organic phase and an aqueous phase. The agent, preferably poorly water soluble, possesses surface active properties and itself serves as a dispersant or a stabilizer for the dispersion. The dispersion is suitable for pharmaceutical, veterinary, cosmetic, and agricultural applications, and is suitable for in vivo delivery, particularly by parenteral routes.
