Thermo-Nicolet Nexus 670 FT-IR Raman spectrometer

The Nexus 670 system integrates FT-IR and FT-Raman spectroscopy capabilities in a single platform to yield vibrational spectra of protein samples. A Smart_ARK HATR accessory equipped with a 45° ZnSe crystal and a trough plate is available to facilitate the collection of FT-IR spectra on liquid or gel samples. Liquid sample_cells with ZnSe windows are also available for measurements at room temperature or, if required, as a function of temperature. KBr films with powdered samples can be pressed with an available Quick_Press. For Raman measurements, holders are available for capillary tubes as well as shortened, 5 mm glass NMR tubes.

First-time users please contact the hub manager to arrange for training on the use of this instrument. Qualified users can book instrument time online with the user name raman_UBC. On the day(s) of your experiment(s), you will need to bring with you the following supplies:

 

  • cleared samples (centrifuged or filtered) if liquid-deuterated solvents may be required
  • liquid nitrogen1
  • sample cell(s) and holder
  • pipetters and pipet tips
  • Parafilm
  • cleaning solutions (water, detergents, acid, alcohol, etc.)
  • Kimwipes (preferably lint-free)
  • USB thumbdrive(s)
  • printer paper

1Liquid nitrogen is required to cool the MCT and Ge detectors. It is up to spectrometer users to supply liquid nitrogen.
