robotic arm to automatically load and unload samples, while “smart grips” ensure consistent testing. It claims that testing is four times more accurate and twenty times faster than manual tensile testing methods.


Molecular fingerprints Raman spectroscopy is a light-based technique that can be used to “fingerprint” materials and to understand chemical bonds and molecular structure. TA Instruments, a subsidiary of Waters Corporation, has introduced the Rheo-Raman Accessory for its Discovery Hybrid Rheometer (DHR) product line to enable simultaneous collection of rheology (flow properties) and Raman spectroscopy data. This combination helps to develop “a deeper understanding of how chemical structure drives material properties, and how macroscopic deformations can have implications at the molecular level,” says the company. The Discovery TMA 450 Thermomechanical Analyzer from TA Instruments measures dimensional changes of materials from -150 to 1000°C. Sample configurations allow testing in expansion, compression, flexure and tension

modes. The instrument can measure a material’s coefficient of linear thermal expansion (CTE), shrinkage, softening, and glass transition tempera- tures. Test options also include stiffness (modulus), damping properties, and creep and stress relaxa- tion over extended experimental time. For applications where fatigue resistance is important, TA Instruments has launched two new
