The ChemLogix line of high-performance benchtop Raman spectrometers from TSI
is intended to deliver maximum flexibility of application. They are available
with a wide variety of sample interface options, so that the user can optimize
the use of the instrument to his or her particular application.
Raman spectroscopy has a unique set of
advantages in process control uses. The spectrometers are fiber-coupled to
probes that will withstand rugged measurement locations. These challenging analyses may include
corrosive, high pressure and high temperature environments through use of
immersion probes, flow-through cells and optical ports. These strategies permit measurements to be
made inside of reactors, fermenters and other synthesis and mixing vessels.
Non-contact use through an optical port permits precise measurements with
minimal risk of sample contamination. Little or no sample preparation is
required and there is no interference from water or carbon dioxide vapor.
Measurements are made quickly, and therefore timed sequential assays can be
used to observe reaction progress, to ascertain endpoints and to understand the
kinetics of processes.
Our Raman devices have excellent signal-to-noise characteristics
and superior fluorescence rejection which enables a wide variety of laboratory
and process control to be performed. These devices are simple and easy to use,
and yet produce data of sensitivity and resolution similar to more expensive
instruments. Additionally, they are
light weight and easy to move between measurement locations.
PRORAMAN-I industrial process Raman
analyzer instrument is driven by a frequency-stabilized diode laser operating
at 785 nm. The spectrometer has a
spectral range of 250-2350 cm-1, and the detector is cooled to
minimize dark current. The resolution of
the system is about 7 cm-1. The graphic user interface of the control and
data acquisition program is shown in Figure 1.
In the top panel, a single spectral acquisition is shown. In the bottom panel, a time series is
portrayed. In this screen, individual peak
heights can be monitored in time, as well as ratios between peaks of interest. Symbion-RX software is available for process
control applications as an option.
EXPERTRAMAN-W is a system with very similar
specifications to the ProRaman, with wider spectral coverage. The spectrometer has a range from 250-3250 cm-1,
with resolution averaged over the entire range of approximately 10 cm-1. As with the ProRaman instrument, the
RamanReader software has automated wavenumber and intensity calibrations, and
can be mated with Grams/AI to perform database searching.
