X-ray diffractometer |
|
![]() |
This device allows for determination of the crystallographic structure of powders, thin-films, and analysis of residual stress. With a maximum voltage 60kV and maximum current of 50mA, the X-ray diffractometer can provide small angle diffraction data with temperature control. |
Scanning Electron Microscope (SEM) and Energy Dispersive Spectrometer
![]() |
SEM provides the image (up to 100000 magnification) of surfaces and three dimensional structures of biological or nonbiological samples. EDS provides qualitative and semi-quantitative information on the chemical composition in microstructures. It also provides the full energy spectrum, mapping and line profile for molecules whose atom number is greater than 5. |
