Hot-stage microscopy (HSM)

Hot-stage microscopy (HSM) service provides direct visual analysis of materials under controlled temperature conditions. Capabilities include:

  • Morphology assessment: Examining compound morphology and particle characteristics.

  • Transformation studies: Observing solid-solid transformations, melting/liquefaction, solidification, sublimation, and evaporation.

  • Compound interactions: Monitoring how different compounds interact, dissolve, or react with each other.

  • Crystallization analysis: Tracking crystal growth and rates.

  • Specialized methods: Utilizing the Kofler mixed fusion method for salt/co-crystal screening.

  • Reaction monitoring: Observing oxidation and other chemical reactions as they occur under heat.

The results will include microscope pictures/video showing the transitions during heating.

Measurement specifications:

  • Temperature range: 25 °C to 375 °C

  • Humidity control: 5-90% RH

Instrument details:

The instrument set-up comprises a heating stage (hot stage) with a sample holder, coupled with a suitable polarized-light microscope and a system that allows measurements of video/pictures and temperature.
