New
Probe Provides a Major Sensitivity Enhancement in Raman Spectroscopy
IRVINE,
Calif., Feb. 25, 2008 – Axiom Analytical
Inc., a leading supplier of sampling
equipment, software, and integrated systems for all forms of vibrational spectroscopy, today announced the introduction
of its RFP-460 Multipass Raman Probe. This probe provides up to an order of
magnitude enhancement in the sensitivity of Raman spectroscopy when used for
the analysis of gases and clear liquids. The principles underlying its
operation were described recently in a paper given by Dr. W. Michael Doyle at
the International Forum on Process Analytical Chemistry (IFPAC), held in
Baltimore Md., January 27 - 30, 2008 (www.ifpac.com/). The paper reported the achievement of marked
sensitivity enhancement, with no undesirable side effects, through the use of a
design previously developed by Dr. Doyle (US Patent 6,795,177 B2). The significantly improved performance was
made possible by combining the multipass approach
with recent advances in interference filter technology.
Raman spectroscopy is a powerful
technique for chemical analysis which combines the specificity of mid-infrared
spectroscopy with the convenience and flexibility of near-infrared. It is based on the use of a focused laser
beam to cause a condensed substance to emit a spectrum of optical radiation
that is uniquely related to its molecular structure. Dr. Doyle’s advance takes advantage of the
fact that Raman scattering is an extremely week phenomenon and is only made
practical by the high energy density of the focused laser beam. Very little attenuation of the laser signal
takes place. In principle, it is thus
possible to pass the same laser beam through a sample more than once. Dr. Doyle’s approach makes it possible to
accomplish this by means of a straight forward modification to Axiom’s standard
Raman probes -- making multi-pass Raman practical, economical, and highly
effective.
Pittcon 2008
The RFP-460 Multipass
Raman Probe will be exhibited at Axiom’s booth (#4323) at the upcoming Pittcon
Conference in New Orleans.
