Nicolet Magna-IR 550 spectrometer is capable of up to 0.125 cm^-1 resolution. The spectrometer is designed for mid-spectral range coverage. Spectra can be collected and summed at a rate of up to 20 scans per second. The bench is controlled via Nicolets’s Omnic software with a full diagnostics analysis system. The source is a tungsten-halogen source. A variable-diameter aperture is used to achieve the maximum spectral resolution. The detector/beamsplitter combination is a DTGS-KBr providing a spectral range of 4000-400 cm^-1.

The bench is continuously purged with dry air reduced CO and moister from a Balston Filter Products 75-20 dry air system. A Harrick Reflection Adsorption attachment allows analysis of monolayer films (RA-FT-IR) and a Harrick Attenuated Total Reflectance attachment allows multiple pass surface analysis at varied sampling depths using a range of angled Ge crystals.
