Fig. 4. Phase identification from CSA-LAG experiments using powder X-ray diffraction.

PXRD patterns of milled products of CSA-LAG at 25 ± 1 °C as a function of solvent activity for (a) theo with h₂o:ace mixtures and b nf with dmf:etoh mixtures. Patterns are coloured black for unsolvated forms, blue for hydrates and green for solvates. Mixtures of solid phases are presented in orange. The phases are identified by comparison of the resulting patterns to simulated PXRD diffractograms from single crystal structures. The theo mixture at 0.6 and nf mixture at 0.1 were further refined by Rietveld refinement.
