RAMAN/PL

Code: 
OPT3
Model: 
Horiba Jobin Yvon LabRam ARAMIS
Location: 
Optical Spectroscopy
Primary Training Contact: 
Operating Procedures: 

The Horiba Jobin Yvon LabRam ARAMIS is a fully automated Raman microscope.  Raman spectroscopy provides highly specific and non-destructive information on molecular vibrations.  There is no  need for sample preparation - the sample is simply placed under the microscope optics and measured.  This system is also equipped with a Photoluminescence detection package.

Applications: 

Raman and PL Spectroscopy for:

  • Pharmaceuticals (compound distribution, phases, combinatorial chemistry, etc.)
  • Semiconductors (stress, contamination, superlattice structure, doping effects, etc.)
  • Polymers (polymorph identification, blend morphology, monomer and isomer analysis, etc.)
  • Life Science (DNA analysis, nucleic acids, cholesterol, lipids, etc.)
  • Physics (ceramics, nanophases, etc.)
  • Chemistry (phase transitions, catalysts, oxides, surfactants, etc.)
  • Carbon Compunds (nanotubes, fullerenes, diamond, etc.)
  • Environmental (pollutants, metal complexes, etc.)
