FAQQ: Can Raman spectra be obtained from solids, liquids and gases?
A: Raman spectra can be obtained from most molecular
samples, i.e. solids, liquids, gels, slurries, powders,
films, etc. Raman spectra can even be obtained from
some metals!
It is possible to obtain Raman spectra of gases. However,
since the concentration of
Q: Can I do Raman spectroscopy on
mixtures?
A: Yes, a Raman spectrum is a spectral “fingerprint”.
If there are a number of different compounds in a
mixture, the resulting Raman spectrum will be a
superposition of the spectra of each of the components.
The relative intensities of the peaks can be used
Q: Is Raman qualitative or quantitative?
A: Raman is both qualitative and quantitative.
As previously mentioned, Raman spectra are unique
molecular “fingerprints”. Spectral library searching
can be conducted to allow qualitative analysis.
Quantitative analysis of a mixture is typically performed
by
Q: Will a pure chemical overload the
detector?
A: No, Raman detectors, or Charge Coupled Device detectors
(CCDs), have a wide dynamic range and users can select
the appropriate exposure time for their sample.
