Raman Spectroscopy

 

When should I use Raman Spectroscopy?

Raman scattering is a spectroscopic technique that is complementary to infrared absorption spectroscopy. In general it is not suitable for analysis of metals and their alloys, but could be very useful in many applications:

  • Chemistry and Plastics

  • Carbon materials

  • Pharmaceutics

  • Life sciences

  • Geology

  • Archaeology

Real-Time Detection

Raman spectroscopy features the following advatanges over mid-IR, near-IR spectroscopy and other analyical techniques:

  • No sample preparation

    No matter the sample is a solid, liquid, powder, slurry or gas; even translucent packing does not interfere. Water and CO2 vapors are very weak scatterers, and therefore purging is unnecessary.
  • Non-Destructive, Con-Contact, Rapid Inspection

    The data harvesting takes only a few seconds, and the non-contact process keeps the analysts safe from exposure to hazardous materials. It is ideal for in situ, in vitro and in vivo analysis.
  • High Selectvity

    Raman spectra are unique molecular fingerprints, "cleaner", narrower and sharper than their infrared counterparts.
  • High Sensitivity

    Several methods of signal enhancement make Raman an ultratrace technique.
  • Portable and Long range Stand-Off Detection

    Integrated with CCD detection technology, it can detect the target sample from a few meters to a few hundred meters away.
  • Miscroscopic Spatial Resolution

    Integrated with a confocal Raman microscope, Raman spectroscopy can offer high sensitivity microscopic analysis with sub-micron spatial resolutions.
