Differential Scanning Calorimeters (DSC) measure temperatures and heat flows associated with thermal transitions in a material. Common usage includes investigation, selection, comparison, and end-use performance evaluation of materials in research, quality control and production applications. Properties measured by TA Instruments’ DSC techniques include glass transitions, “cold” crystallization, phase changes, melting, crystallization, product stability, cure / cure kinetics, and oxidative stability.

Differential Scanning Calorimeters (DSC)
Thermogravimetric Analyzers
- Thermogravimetric analyzers (TGA) measure weight change (loss or gain) and the rate of weight change as a function of temperature, time, and atmosphere.
- Thermogravimetric data is critical to setting proper temperature limits for Differential Scanning Calorimetry method development.
- Other common usages include thermal and oxidative stability of materials, moisture and volatile contents, composition of multi-component materials, decomposition kinetics and estimated lifetime of a product, and effects of reactive or corrosive atmospheres.
Simultaneous Thermal Analyzer
DSC/TGA system that delivers the purest real-time simultaneous heat flow and weight data possible.
Dynamic Mechanical Analyzers
- Dynamic Mechanical Analysis measures the mechanical properties of materials as a function of time, temperature, and frequency.
- In addition to basic material properties, DMA also quantifies finished part characteristics, reflecting the important contribution that processing has on end-use performance.
- DMA is commonly used to measure glass transition temperatures and secondary transitions, orientation caused by processing, cold crystallization, cure optimization, filler effects in composites, and much more.
- DMA provides an accurate measure of material stiffness (modulus) but also other important mechanical properties such as damping, creep, and stress relaxation.
