The laboratory performs operando and in-situ measurements with Fourier transform infrared (FTIR) spectroscopy, which are a powerful tool for detailed study of the mechanism of adsorption and catalytic processes. The results of these studies can be used as a foundation in the design of efficient materials for clean technologies (gas separation, purification, storage, sensing, catalysis, etc.). Potential partners and clients in the laboratory can be research teams and business representatives with interests in the field.
SYSTEM FOR OPERANDO/IN SITU SPECTROSCOPY
The system includes:
– FTIR spectrometer Thermo Scientific Nicolet iS50R (fast scan, MCT-A detector);
– IR reaction cells from Harrick Scientific for in-situ/operando measurements: (i) high temperature transmission cell and (ii) high temperature diffusion reaction chamber, used in conjunction with the Praying Mantis accessory;
– Exhaust gas analyzers: (i) gas chromatograph Thermo Scientific Trace 1300 Series and (ii) mass spectrometer Hiden Analytical HPR-20 R&D;
– Gas flow set-up: Bronkhorst EL-FLOW Prestige mass-flow controllers, gas lines, valves.
Operando methodology allows spectroscopic characterization of materials during their operation in various processes, e.g. in catalytic processes with simultaneous measurement of catalytic activity and selectivity. On the contrary, in-situ spectroscopy deals with the analysis under controlled environment.
