Analytical Capabilities

EPT has upgraded its scientific instruments in recent years. From purchases of new instruments to replacements of aging instruments, EPT has ensured that the research efforts of its scientists and engineers benefits from the cutting edge of instrumentation.


A Hitachi S-3400 SEM with backscatter and EDAX serves the entire company. The impressive high magnification of the S-3400 allows characterization of nanomaterials for Li-ion research, while impurities can be identified in newly-manufactured materials via the EDAX system’s elemental identification.


A laser flash analyzer allows measurement of thermal properties for multiple materials. Thermal batteries especially rely upon accurate thermophysical property information to predict performance and lifetime. The laser flash analyzer measures thermal diffusivity, specific heat and thermal conductivity over a wide temperature range.


A Rigaku X-Ray Diffraction system delivers accurate structural information on the materials manufactured and purchased by EPT. This ensures both the chemical and structural makeup on an atomic level meets the exacting requirements of EPT’s manufacturing processes.

Chemical identification of various materials is achieved through a suite of instruments. From a gas chromotograph-mass spectrometer for materials in solvents; to a Fourier Transform Infrared spectrometer for studying liquids, gases or solids; to DSC and TGA instruments to determine the presence and amount of impurities through observed reactions and mass changes, EPT is able to perform in-depth and complete studies of the materials being developed in-house to meet the needs of our customers and partners.
