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)

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.

Autolab/Pgstat12 with FRA module
      Autolab/Pgstat12 is low/current low noise modular potentiostat/galvanostat capable of measuring maximum 250 mA, with a compliance voltage of 12 V. The instrument is equipped with a FRA module allowing to perfrom potentiostatic and galvanostatic impedance measurements in a frequency range from 10mHz to 1 MHz. In connection with ECD module, the apparatus is designed to measure currents in the range as low as 100 pA with resolution of 0.3fA. Instrumentation is used for the determination of electrical properties of solids by DC techniques, AC voltammetry, and impedance spectroscopy.
