Thermo Nicolet 6700 FTIR Spectrometer
Thermo Scientific Genesys 5 UV-VIS Spectrophotometer
Fourier Transform Infrared (FTIR) Spectroscopy
The new Thermo Nicolet 6700 FTIR spectrometer at Southwest Research Institute (SwRI) offers high sensitivity, resolution, and data acquisition speed to detect and analyze unknown specimens. The FTIR can be operated in either a standard or attenuated total reflectance (ATR) mode. The FTIR has a range of 400 to 4,000 cm-1. Samples can be either thin films, bulk solids, or liquids.
Ultraviolet-Visible (UV-Vis) Spectrophotometry
We rely on UV-Vis spectrophotometry at SwRI to identify unknown compounds occurring in chemical, pharmaceutical, and environmental processes. Our Thermo Spectronic Genesys 5 UV-Vis spectrophotometer operates at wavelengths between 200 and 1,110 nanometers using a tungsten-halogen lamp and split-beam dual detectors. As many as 7 samples plus a blank can be evaluated at one time.
Staff at SwRI have used UV-Vis spectrophotometry to detect the presence of salts at concentrations of almost 0.5 ppm and to perform U.S. Pharmacopeia (USP) assays.
Also available at SwRI:
- Raman spectroscopy
- Gas chromatography/mass spectrometry (GC/MS)
- Liquid chromatography
- Nuclear magnetic resonance (NMR)
