Hot Stage Microscopy

Material analysis under temperature variations​

Hot Stage Microscopy (HSM)

Hot Stage Microscopy (HSM) is a powerful technique used to visually observe the behavior of pharmaceutical materials as they are heated. It provides valuable insights into phase transitions, melting points, and crystallization processes.

At Particle Analytical, we utilize the Línkam FTIR600 which captures microscope images during heating.With a temperature range from 25°C to 375°C and precise humidity control from 5-90% RH – our system delivers detailed visual and thermal analysis of pharmaceutical materials under controlled environmental conditions. This system in combination with Raman microscopy gives the spectroscopic support to conclusions made based on visually observed changes.

How Particle Analytical can assist with Hot Stage Microscopy (HSM)

  • Phase Transition Analysis

    Visually observes phase transitions such as melting, crystallization, or polymorphic changes during heating, providing critical data for formulation development.

  • Temperature and Humidity Control

    Monitors material behavior under varying temperature and humidity, essential for stability studies and predicting real-world performance.

  • Crystallization Studies

    Helps assess crystallization behavior under controlled conditions, aiding in the selection of stable crystalline forms for drug formulations.

  • Formulation Development

    Supports the optimization of formulations by providing real-time insights into how materials behave under thermal stress.

  • Quality Control Support

    Ensures that materials exhibit expected thermal behavior, helping to maintain consistency and compliance across batches.
