TOOLS & INSTRUMENTS

# Nexus 670 ThermoNicolet Fourier Transform Infrared Spectrometer

We currently use a high resolution (0.1 cm-1) Nicolet Nexus 670 that is flexible in both its current iteration and is upgradeable for future needs. The optics are fully optimized and computer controlled for ease of use. Changing spectral range is as easy as removing an optical component and placing the new one into its position. The software automatically updates ranges, sensitivity and parameters. Some of this is sensitive, so for first time users we ask that they approach us for a quick run through, especially if optics are to be switched out. The main components are listed below with the available options. Please see manual.

## Specifications/Capabilities

                    - Source: Everglo (gives good/fair intensity over all wavelengths of interest to neutron scientists)
                    - Beam Splitters: KBr and Far-ir
                    - Detectors: DTGS with KBr (12,000 cm -1  to 350 cm -1 ) or polyethylene (700 cm -1  to 10 cm -1 ), MCTA liquid nitrogen cooled for high sensitivity (11,700 cm -1  to 600 cm -1 )
                    - Purge: The spectrometer is continuously purged with dried, CO2-free air.

Information on the environment control can be found at the old site.
