Vibrational Spectroscopy Laboratory

The vibrational spectroscopy lab is equiped with both a visible Raman (with FTIR unit) and a UV Raman Laser Microprobe. The visible Raman has both 632 nm and 514 nm laser excitation. The UV system has both 514 nm and 244 nm laser excitation. Both units offer excellent spatial resolution (approximately 1 um) for the micro-analysis of mineral phases, melt and fluid inclusions. Analyses can be carried out over a wide range of temperatures when used in conjunction with a Linkham heating/cooling or Joule Thompson cooling stages. The UV system allows for the analysis of many materials (e.g. organic compounds) that fluoresce strongly under visible radiation.
