The Analytical Spectroscopy Laboratory provides centralized care of, and training on, a variety of instruments for use by the graduate research program. Researchers may have access to instruments which are not available in their own labs because they are expensive or used infrequently. New ideas can be tested. Results and publications generated from ASL instruments can be used to justify proposals for instruments for a Principal Investigator's own laboratory.
The Lab Manager trains the users how to operate the instruments, and is available for advice on how to get the best results out of the measurements. Users who are certified have around the clock access. Descriptions of the instruments and their capabilities, and procedures and policies for using them are listed below.
(Note: The Circular Dichroism spectrometer, the Polarimeter, and UV-Visible spectrometer are now housed in the Biophysical Interaction and Characterization Facility)
Bruker EPR | B 081 CBEC
Renishaw inVia Raman & Smiths IlluminatIR IR Combined Microprobe | B 075 CBEC
Bruker EMXPlus Electron Paramagnetic Resonance Spectrometer
This is a standard Continuous Wave Electron Paramagnetic Resonance spectrometer, for the detection of unpaired electron spins. The standard temperature controller regulates the temperature from 100K to 100C. A helium refrigerator may be available for work down to 4K. Samples may be illuminated while in the cavity. (This instrument is an update from the previous ESP300 spectrometer.)
This permits recording of mid-IR and Raman spectra on exactly the same spot using the same instrument system. IR and Raman spectral maps can also be recorded on exactly the same area. Temperature controlled sample cells will permit temperatures to range from 100K to 1500C
