Smith G. (2016) The Application of Through Vial Impedance Spectroscopy (TVIS) for Process Parameter Determination in Freeze Drying Method Development. Podium presentation at PDA Europe Pharmaceutical Freeze Drying Technology; 2016 Sept 27-28, Strasbourg, France
The presentation starts with a description of the through vial impedance spectroscopy (TVIS) and the measurement system before going on to describe applications in the determination of various process parameters and related phenomena:
Vial heat transfer coefficient (KV)
Dry layer resistance (RP)
Ice nucleation (onset of ice growth)
Glass transition
Eutectic crystallization
