Electron microscopy and EDX microanalysis

The X-ray microanalysis is non-invasive and can be performed in a volume of µm³ order of magnitude. The diameter of  the area analysed can be from 0.05 µm to 5 mm. It is able to find and determine the elements with atomic numbers from 5 to 92 (from boron to uranium)

Electron microscopy and EDX microanalysis

The SOLVER PRO-M model is suited for:

• Large XYZ scanning range (from atomic resolution up to 100 х 100 µm²) for samples of solids with maximal size of 100 x 20 mm² or a dried suspension on a HOPG surface
• Integrated optical video system with resolution of 3 µm
• Statistical values of roughness (RMS) and grains/pores analysis
• In ambient air:
  • Topological image - STM (Scanning Tunnelling Microscopy)/ AFM (contact + non-contact + semicontact modes)
  • Mapping of mechanical behaviour -  Phase Imaging/ Force Modulation Mode/ AFAM (Atomic Force Acoustic Microscopy)/ Adhesion Force Imaging
  • Mapping of electromagnetic behaviour -Spreading Resistance Imaging/ Magnetic Force Microscopy/ Electric Force Microscopy/ Kelvin Force Mode
• Applications
  • New materials/ Thin Film/ Polymers/ Semiconductors/ Defect detection/ Biological samples

Optical microscopy

Magnification 50 – 500x. Light source (100 W halogen lamp) works in both transmittedand reflex mode. Bright filed, dark field and polarized technique is available. Optical stage can be easily changed by heating stage. Heating stage is supplied by programmable unit with possibility of regulation in the temperature range – 196 - +600 ^oC; available heating rate 0.01 – 130 ^oC/min. Isothermal regime allows nine different ramps. Optical microscope is connected with computer, camera and CCD camera.
