Fig. 8 — Comparison of the critical solvent activities obtained from CSA-LAG (y axis) versus slurrying (x axis). A perfect linear fit y = x with an R squared value of 0.975 indicates a very strong agreement for the thermodynamic boundaries obtained from the two different methods. Horizontal and vertical error bars represent the resolution of phase boundary determination, showing the range of controlled water activities tested above and below the transition point.
