Thermal analysis is the study of the relationship between a sample property and its temperature. Applications include:
- Evaluation of thermal stability
- Detection of the glass transition
- Determination of the amount of volatile matter in a sample
- Measurement of melting point temperature and enthalpy
- Analysis of the viscoelastic behaviour
Want to learn how we do thermal analysis?
Browse our thermal & polymer characterisation library to learn how we detect glass transitions, how we measure molecular mass distributions and more thermal analysis methods.

We host the following thermal analysis instruments:
|Technique||Instrument||Temperature range||Acquisition program||Comment|
|Thermogravimetric analysis (TGA)||Setsys Evolution TGA 16/18 by Setaram||30°C to 1000°C||Calisto||coupled with a mass spectrometer for evolving gas analysis|
|Differential scanning calorimetry (DSC)||DSC Q20 by TA Instruments||-80°C to 400°C||Q series||for solid samples|
|Dynamic mechanical analysis (DMA)||DMA1 by Mettler Toledo||-170°C to 600°C||STARe||for films and bars in bending, tension and compression|
We also provide Size Exclusion Chromatography (formerly know as Gel Permeation Chromatography, GPC) that measures the distribution of molecular masses in a polymer. The instrument is a 1260 GPC/SEC MDS from Agilent, equipped with:
- triple detection: differential refractive index, viscometer and dual angle light scattering;
- two columns PLgel 5 µm MIXED-D 300 x 7.5 mm (with a guard column PLgel 5 µm MIXED Guard 50 x 7.5 mm);
- tetrahydrofuran (THF) as mobile phase;
- columns and detectors all maintained at 35 °C;
- calibration using a set of polystyrene or poly(methyl methacrylate) (PMMA) standards.
