is essential for characterizing any material that has properties affected by temperature. In fact, materials have a “fingerprint” that can be identified with a thermal curve.
Performing temperature programmed studies leads to a detailed understanding of how thermal conditions affect stability, degradation, composition, phase change, and even reaction kinetics.
In addition to temperature studies via chemisorption techniques, PTA utilizes thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), which apply to a wide range of materials and applications. These techniques also require a minimal sample size (less than 50 mg).
Thermogravimetric Analysis (TGA)
is a technique utilizing a highly sensitive balance to measure a sample’s change in weight within a programmed time, temperature, and gas environment.

Differential Scanning Calorimetry (DSC)
is a technique which measures heat flow into or out of a material based on a controlled thermal profile. These measurements can provide both qualitative and quantitative information about physical and chemical changers that include endothermic and exothermic process or changes in heat capacity.
