Over the past few decades, a number of analytical instruments have been developed for the characterization of product formulations intended for Lyophilisation. Freeze-drying microscopy (FDM) is now used routinely to determine the critical temperature at which the product may collapse during primary drying (Tc) whereas a combination of differential thermal analysis (DTA) with electrical impedance analysis has been used to study the critical temperatures of a sample in a frozen state (i.e. the glass transition, ice crystallisation and eutectic melting temperatures). In this study, a combination of impedance spectroscopy with freeze-drying microscopy (Z-FDM, G. Smith, 2019) has been reported for the first time.
