Surface Analysis

In the laboratories of the Jagiellonian Center of Innovation, we offer a broad range of surface analysis services based mainly on Raman spectroscopy and electron microscopy.

Laboratory of Raman Spectroscopy

The laboratory is equipped with high class Raman spectrometer (Witec alpha 300 RSA+) with a confocal microscope, an atomic force microscope (AFM) and a polipherometer. All measurements are performed on the same measurement table, hence transfer of the sample is not necessary.

The instrument allows for:

  • imaging of diffusion of chosen substances in tablets
  • measuring homogeneity of solid formulations
  • analysis of sample topography and confocal measurements
  • chemical compound testing to allow for the differentiation between their polymorphic forms
  • studying permeability of semi-liquid formulations, depending on the time and conditions of exposition

Laboratory of Scanning Electron Microscopy

The scanning electron microscope (Mira3-FEG-SEM, Tescan) with field emission (Schottky emitter) equipped with X-ray energy dispersion spectrometer EDX (Oxford Instruments). The microscope enables working in high, low and variable vacuum.

The microscope is equipped with:

  • secondary electron detector for high vacuum experiments (Everhart-Thornley detector)
  • secondary electron detector for low vacuum experiments LVSTD (7–500 Pa)
  • back-scattered electron detector (BSE) for high and low vacuum experiments
  • cooling table (Peltier) working in the temperature range from -30°C

The laboratory can study conductive materials (metals and alloys), non-conducting samples, such as ceramics, polymers as well as composite and organic materials.

The instrument allows for:

  • imaging of conducting and non-conductive samples in high and variable vacuum
  • research on the morphology and chemical composition of non-conductive samples in low and variable vacuum
  • qualitative and quantitative analysis of elements with atomic number Z ≥ 5 – surface, point, linear analyses, as well as maps of element distribution in microareas, with the use of EDX spectrometer
  • studying biological samples in situ, observation of dynamic changes, such as sample hydratation and dehydratation; observation of phase transitions is also possible (Peltier's table)
  • observation of interactions between the sample and the changing environment
