Point Analysis
The Raman Microscope takes utilizes the phenomenon
of Raman scattering to extract information about bonding in
materials. The Raman microscope provides micrometer scale
resolution allowing for analysis of micrometer-size particles (or in
some cases smaller). Through interpretation and comparison
against our Raman spectral libraries, which contain several thousand
compounds, we can use the information in the Raman spectrum to
identify unknown particles or characterize the properties of
materials. This system is equipped with two lasers (785 nm and
532 nm), stage mapping, and confocal analysis.
Raman Mapping
Raman mapping provides a way to carry out time,
depth or area resolved maps of samples to follow the progress of
chemical reactions as they occur, look for heterogeneities in
surfaces or changes in surface chemistry or changes in a sample with
depth.
SERS
Although surface enhanced Raman spectroscopy
(SERS) is often considered a research method, we have utilized the
resonance scattering technique to great benefit in practical
application on numerous cases.
Spectral Databases
Due to the lack of commercially available Raman
databases, Microtrace has developed several of its own Raman
databases covering a variety of compounds, with a particular
emphasis on the identification of colorants (pigments and dyes).
