CPACT
recently carried out an evaluation of the Tornado Hyperflux Pro Raman
spectrometer for Clairet Scientific. The evaluation compared results with
previous work done on older Raman spectrometers, and also tried some new
applications. The new virtual slit design of the Tornado instrument
dramatically increases the sensitivity of the Raman measurements.
Very high
signal-to-noise performance was shown in the study with an 11-fold improvement
in the lower limit of detection for a metal salt in solution. In a
crystallisation experiment the onset of crystallisation was detected five
minutes earlier than in previous work. In dynamic powder blending experiments
there was also a significant improvement in the limit of detection for aspirin
in Avicel.
The study successfully
demonstrated how the new generation of Raman instruments is improving the
sensitivity of the technique and enabling new applications in this growing
field.
