Thermo-optical analysis (TOA) allows visual observation of the physical changes that occur in a sample as it is heated, cooled, or held isothermally. By revealing changes in the optical properties of a substance, this technique offers insights into structural and morphological changes that may not otherwise be detected.
TOA using a hot-stage microscopy system is a widely-used technique. When combined with differential scanning calorimetry (DSC), the heat flow is simultaneously measured for a more comprehensive analysis.
Typical events observed using this technique include melting and crystallization, stability, polymorphism, and release of solvents. These can be investigated with just a few milligrams of sample.
In this webinar, you will gain an understanding of the principles behind TOA, learn about METTLER TOLEDO’s hot-stage instruments, and explore practical applications for different industries.
We conclude with a live Q&A session, so don’t forget to prepare your questions for our experts!
