Factor freeze-drying diagram

Figure 3.5 is a diagram of the freeze drying of a factor VHI-solution (the same solution... 

Fig. 6.12 Critical PS thickness above which cracking of the PS film during evaporation of water is expected, according to Eq. (6.9). Note that drying in pentane or ethanol increases the critical thickness by a factor of about 26 or 11, respectively. Inset Cracking can be avoided by freeze drying (1) or critical point drying (2), which removes the solvent without crossing the fluid-gas boundary in the phase diagram (3).
