These include: (i) the peak imaginary amplitude, C"PEAK, which is a direct measure of ice mass in the vial, and (ii) the peak frequency, FPEAK, which is sensitive to a change in the shape of the ice interface.</p></div></div></div><div><br></div> 2020-05-06 12:39:22 Freeze Drying Through Vial Impedance Spectroscopy Pharmaceutical Sciences
