Materials Analysis
The Materials Analysis Laboratory at ARC provides thermal, magnetic, electrical, and electron paramagnetic resonance (EPR) characterization services for a wide range of materials, including thin films, solids, liquids, and nanoparticles. Our facility supports researchers across disciplines by offering precise measurements of fundamental material properties, such as thermal stability, heat capacity, magnetic susceptibility, electrical resistivity, and the presence of unpaired electrons, critical to both scientific discovery and industrial applications.
Services:
- Thermal Analysis – Characterization of phase transitions, stability, and heat capacity.
- Magnetic Property Measurements – Temperature- and field-dependent analysis of magnetic susceptibility, hysteresis, and Néel temperature.
- Physical Property Measurements – Heat capacity, thermal transport, electrical resistivity (DC & AC), Hall effect, and magnetic characterization.
- Electron Paramagnetic Resonance (EPR) – High-sensitivity detection of paramagnetic species, temperature-dependent analysis, and cryogenic capabilities.
Our lab operates in both full-service and self-use modes, allowing researchers the flexibility to conduct their own experiments or collaborate with our experts for tailored analysis. We provide expert guidance in experimental design and data analysis.
Instruments:
- TA Q500 TGA – Thermal stability, decomposition kinetics, and volatile component analysis (ambient to 1000°C).
- TA Discovery 2500 DSC – Glass transition, melting points, crystallinity, heat capacity, and cure rate analysis (-80 to 350°C).
- Quantum Design MPMS3 – 7T superconducting magnet, SQUID AC susceptibility, VSM (1.8K-1000K), electrical transport, and horizontal rotator.
- Quantum Design Dynacool PPMS – 9T magnet, temperature control (1.8K-400K), DC resistivity, electrical and thermal transport, heat capacity, horizontal rotator.
- Bruker ELEXSYS ESR-500 X-band CW EPR spectrometer – Dual-band and high sensitivity probe options are available along with Bruker Cold Edge Stinger and Oxford cryostat for VT down to 4K.
