FTIR: Fourier-transform infrared spectroscopy of gaseous analytes and sensor materials
responsible person: Dr Eng. Marcin Procek
We conduct research that includes:
- Infrared absorption spectroscopy of gases and volatile organic compounds (VOCs) using multi-pass measurement cells with optical path lengths ranging from 1 cm to 10 m, at temperatures from room temperature up to 150°C;
- Infrared absorption spectroscopy for qualitative analysis of materials using the attenuated total reflectance (ATR) technique in FTIR, with the option of elevated temperature operation up to 180°C;
- Spectral characterization of detectors and filters in the SWIR, MWIR, and LWIR radiation bands (400 nm – 28 µm);
- FTIR analysis of analytes using separation techniques with a GC-IR measurement module; measurements are supported by GC-MS techniques;
- Configuration and testing of open-patch sensor systems, as well as the possibility of testing laser-based sensor systems using QCL and ICL sources with photonic and thermal detectors;
- FTIR spectral studies supported by complementary techniques such as SEM-EDS, Raman spectroscopy, and UVC-Vis-NIR spectroscopy.
