Laboratory Raman Spectroscopy

Meg Tivey (WHOI-MC&G), Chip Breier (WHOI-AOPE)

I have laboratory laser Raman spectrometer with microprobe (see picture at right) and a 532 nm laser. This system can be used for laboratory analyses of minerals, liquids and gases. Two samples cells allow liquids and gases to be analyzed at pressures up to 400 bar, and temperatures from 0-300 C. Work to date has focussed on hydrothermal vent minerals and dissolved gases.
