Understanding Solid State Behaviour

Hot Stage Microscopy

Objective

  • Viewing the sample while heating permits observation and identification of phase changes such as melting, desolvation and recrystallization
  • Can be correlated to DSC and VT XRPD data
  • <1 mg of sample needed

Case A: Desolvation (images a to d) and melting of desolvated material (images e to h)

Case B: Melting of crystalline material (images a to e) and recrystallization during cooling to  room temperature (images f to g)
