AAPS annual meeting and exposition. San Diego, November 10th – 14th. Poster Presentation on November 12th 

This poster described the first time that through-vial impedanace secptroscopy (TVIS) has been used to study the phase separatonof two formulation additives usied in certain freeze-dried drug product solutions.
