Thermal Analysis

Thermal chemistry analyses are used to determine melting points, coefficients of thermal expansion, glass transitions, solidus-liquidus and specific heat of various materials.

Lucideon uses two state-of-the-art Q-Series thermal analysis instruments from TA Instruments to offer thermogravimetric analysis (TGA), thermomechanical analysis (TMA), and differential scanning calorimetry (DSC).

The Simultaneous TGA and DSC (SDT) Q600 provides simultaneous measurement of weight change (TGA) and differential heat flow (DSC) from ambient to 1500°C. It is particularly useful for the determination of filler content in plastics, rubbers and coatings; solidus and liquidus in metals; braze or solder melting properties; moisture content; thermal decomposition temperatures; cure reactions and other important material properties.

The Thermomechanical Analyzer (TMA) is useful for measuring dimensional changes under conditions of controlled temperature, atmosphere, time and force. This instrument is capable of running experiments from -150°C to 1000°C. Force can be applied in flexure, compression or tensile modes.

Materials, such as solids, coatings, foams, films, and fibers, can be characterized for expansion, penetration, compression, tension, and 3-point bending. Lucideon uses TMA to measure material properties such as expansion coefficient, glass transition, softening and melting behavior, delamination, shrinkage and flexure, and to generate stress/strain information for our clients.

Standalone DSC is also available at Lucideon, and is used for differential heat flow experiments requiring maximum precision and accuracy. DSC answers a range of questions relatively quickly, such as melting temperature, enthalpy of melting or crystillization, phase change in material, or isothermal kinetics.
