Raman spectroscopy for the study of biological organisms (biogenic materials and biological tissues): a valuable analytical tool

Further applications of Raman in the biological world are discussed in “Raman spectroscopy for the study of biological organisms (biogenic materials and biological tissues): a valuable analytical tool” by Malvina Orkoula and Christos Kontoyannis. In this article, the applications are more medical and show how Raman spectroscopy can provide more information on parts of our bodies from kidney stones to osteoarthritic hips than the traditionally used techniques of FT-IR spectroscopy and X-ray diffraction.

Emerging sampling approaches for Raman analysis of foods

“Emerging sampling approaches for Raman analysis of foods” by Nils Kristian Afseth, Matthew Bloomfield, Jens Petter Wold and Pavel Matousek describes how a number of instrumental developments are enabling Raman spectroscopy to find increasing applications in food analysis. They show how Spatially Offset Raman Spectroscopy (SORS) is being used to analyse quality parameters in salmon, including the content of fat, its fat composition and the content of carotenoids. Traditionally, the preserve of NIR spectroscopy, Raman may increasingly be used for the analysis of food and other biological matrices.

Spectral database for postage stamps by means of FT-IR spectroscopy

“Spectral database for postage stamps by means of FT-IR spectroscopy” by Eleonora Imperio, Gabriele Giancane and Ludovico Valli will be of great interest. As well as helping to detect forgeries, FT-IR has been used to create a database which also charts the history of the technology used to create stamps. Quite rightly, they are considered by many to be works of art.

Membrane inlet mass spectrometry for in situ environmental monitoring

User Rating: / 4
PoorBest 

“Membrane inlet mass spectrometry for in situ environmental monitoring” by Simon Maher, Fred Jjunju, Iain Young, Boris Brkic and Stephen Taylor looks at a technique that is 50 years old but is now being applied for field analysis. As well as a brief overview of the technique, they show how it can be used to monitor oil-in-water levels before discharge from oil termini.
