Nicolet™ iS50 FTIR Spectrometer equipped with two MCT/B and two DTGS detectors is a core of sophisticated system exploited to investigate surface chemistry of nanomaterials. In-situ set-up (shown in the Figure) is dedicated for probing nature, concentration, accessibility, thermal stability of surface functional groups, acidic, basic and redox sites, as well as dispersion of metallic active phase in heterogeneous catalysts.

Set-up for in-situ FTIR characterization of nanomaterials: 1) FTIR spectrometer; 2) IR cell composed 3) vacuum line 4) thermocontroller; 5) pressure controller connected to three Pfeiffer™ Vacuum gauges.
