Thermal Analysis and Soft Materials Characterization

Thermal analysis covers a range of techniques used to determine the physical or chemical properties of a substance as it is heated, cooled, or held at constant temperature. MRL’s Thermal Analysis and Soft Materials Characterization suite hosts a wide range of instruments for your research.

Techniques

Center for Excellence in Soft Materials

Techniques for evaluating materials' properties include particle size analysis, Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Dynamic Mechanical Analysis (DMA), and Differential Thermal Analysis (DTA).

Shimadzu DTA-50 Differential Thermal Analyzer (DTA) raremy mali85 133 MRL Center for Excellence in Soft Materials

Differential Thermal Analyzer (DTA) uses a two-pan system to measure the heat flux difference between an empty pan (or one with a reference material) against the temperature of a sample of specific weight. The DTA-50 system uses temperatures in the range between room temperature and around 1400 oC to determine thermal transitions such as glass transitions, crystallization, phase changes, melting, stability, cure kinetics, etc. While it is not as sensitive as a differential scanning calorimetry (DSC), it is more versatile for harder materials, as our DSC system cannot operate above 400oC. The DTA-50 instrument is calibrated to 1100oC for accuracy.

Malvern Zetasizer raremy mali85 133 MRL Center for Excellence in Soft Materials

The Zetasizer uses laser technology to measure both size and zeta-potential. The size measurement is limited to 0.6nm to 6 microns and uses reflective light and Brownian motion. Our instrument uses a 633nm red laser fitted to do both front and back light scatter. The instrument is equipped to assist with specimen quality evaluation, automatic charts, data processing, and various report formats for the user.

Q800 Dynamic Mechanical Analysis (DMA) raremy mali85 133 MRL Center for Excellence in Soft Materials

Dynamic Mechanical Analysis (DMA) measures mechanical properties of samples. Its principal uses include measurement of a material's Young's modulus or viscoelastic properties as a function of temperature (or time). Testing can be performed in either tensile or cantilever bending geometries.

Q50 Thermogravimetric Analysis (TGA) raremy mali85 133 MRL Center for Excellence in Soft Materials

Thermogravimetric Analysis (TGA) measures weight changes in a material as a function of temperature (or time) under a controlled atmosphere. Its principal uses include measurement of a material's thermal stability and composition. The Q50 features a vertical beam balance design (sample capacity: 1000 mg) that supports precise TGA (balance sensitivity: 0.1 µg) measurements.
