Analytik, leading suppliers of innovative analytical
instrumentation, report on the work of Dr Jonathan Burley from the University
of Nottingham. He is using one of the smallest Raman spectrometers in his
academic research and teaching focusing on its ability to provide rapid sample
analysis
.
Dr Jonathan Burley is a lecturer in Pharmaceutical Nanotechnology at the
University of Nottingham. His research interests focus on measuring and
understanding change in pharmaceutical materials. This includes changes that
occur with time, temperature, position in sample, addition of solvent, etc.
Phenomena of interest include crystallisation, polymorphism, hydration,
dehydration, mapping of components in tablets and other drug delivery vehicles,
formation of salts and co-crystals.
While he uses a multitude of analytical techniques, he is particularly
interested in those which produce rapid spatial analysis results when mapping
tablets and complex drug delivery vehicles. This is also recognised as
important for the quality of control of medicines and understanding controlled
release processes. One new technique being applied in the laboratory is the
RAPID.ID palm-sized Raman spectrometer supplied by Analytik.
Speaking of his work, Dr Burley said "The new Raman system is really
impressive. We are using the spectrometer for monitoring laboratory reactions
in solvents to see if we can remove the requirement for NMR, TLC and other
techniques. Motivation is around green chemistry and simply making things
easier for chemists to provide rapid information output such as kinetics,
extent of reaction etc. I am using the fact that this is a miniature
spectrometer, convenient and reliable to use."
For students, this is a great introduction to Raman spectroscopy as often
access to benchtop systems is restricted to research use. The compact and
rugged design of the RAPID.ID makes it an ideal screening tool to help with the
most routine of testing challenges helping to make Raman spectroscopy accessible
to all.
Speaking about applications for the RAPID.ID, Analytik's Marketing Manager, Tom
Greenwell, said handheld spectrometers are becoming widely used in many types
of laboratory from the teaching lab through to routine quality control in
industry. For example, in forensics, you may identify alcohol, paint,
fertiliser and drugs while in the pharmaceutical industry, it is possible to
identify counterfeit products and packaging. Linking to the green motivations
of Dr Burley, we are also finding applications to help identify polymers for
recycling."
