A new interpetation of Raman spectra enables biological carbon to be distinguished from other sources.
Raman spectroscopy sensor can determine which tissue layer an epidural needle is in and ensure correct delivery of the anaesthetic.
Rigaku Analytical Devices has enhanced its Progeny ResQ handheld chemical identification analyser with a new feature.
Horiba Scientific’s Omni silver TERS probes for nanoRaman systems enable all modes of TERS operation.
It is not every issue that one of our articles starts with a quotation in medieval English, and it is appropriate as two of our articles cover the use of spectroscopy in cultural heritage. This is yet another field where the rich information provided by spectroscopy, along with its non-destructive nature (for many techniques), portability and ability to generate chemical images make it the answer to many questions. Kate Nicholson, Andrew Beeby and Richard Gameson are responsible for the medieval English at the start of their article “Shedding light on medieval manuscripts”. They describe the general use of Raman spectroscopy for the analysis of historical artefacts, and, in particular, their work on medieval European manuscripts and 18th century watercolour pigments. They stess the importance of checking the actual laser power density to avoid damage to priceless artefacts.
This article looks at the use of Raman and XRF spectroscopies to investigate the different deterioration processes caused by marine aerosols. These techniques can detect the decay compounds and the original composition of the different materials from historical buildings close to the sea, which can then be used to explain the reactions that take place on them. This helps in the development of remedial actions and preventive conservation strategies for historical buildings.
Entries for the IRDG Chalmers and Dent Student Travel Award for a PhD to present their research at the SciX meeting.
The Eagle Raman-S spectrometer platform from Ibsen Photonics is designed for OEM integration into weak intensity Raman solutions at 785 nm or 830 nm excitation.
Renishaw have added Bruker’s Dimension Icon atomic force microscope to the range of instruments supported by their inVia confocal Raman microscope.
As you will have noticed from this issue’s cover, we are making a colourful start to 2016. In the first article on “The analytical niche for Raman spectroscopy in biological pigment research”, Daniel Thomas and Cushla McGoverin suggest that Raman spectroscopy may have a particularly valuable role in pigment biology research. Pigments are almost universal in biology and are the basis of much of what we find attractive in flowers, birds and sea life, such as the fan corals on the cover. The authors show how Raman spectroscopy can be used to quickly confirm the presence of a pigment as well as providing more detailed knowledge about unknown pigments.
A technique to combine the ultra-sensitivity of surface enhanced Raman scattering (SERS) with a slippery surface invented by researchers at Pennsylvania State University, University Park, PA, USA, will make it feasible to detect single molecules of a number of chemical and biological species from gaseous, liquid or solid samples.
This product focus is on Molecular Spectroscopy.
Horiba Scientific’s ParticleFinder offers a user friendly tool for automated location, characterisation and Raman analysis of particles.
Laser Detect Systems is introducing the new edition of their B-SCAN—a Bottled Liquid Scanner.
The new TacPac accessory can be used with SERS consumables to identify street heroin.
Raman, FT-IR and ED XRF discover interesting detail of the dying in the 19th century, and maybe about trade links between Europe and Australia.
ST Japan-Europe has released a new collection of gemstone Raman spectra.
In the Tony Davies Column, Tony looks at “Raman imaging of difficult surfaces”. He looks at a number of different approaches to dealing with uneven samples, as well as reviewing instrumental improvements that have made Raman imaging a viable analytical and diagnostic tool.
Scientists at EPFL have shown how a light-induced force can amplify the sensitivity and resolution of SERS for the study of single molecules.
A team of researchers has demonstrated a new type of imaging system based on Raman spectroscopy that reveals the chemical composition of living tissue for medical diagnostics and cellular studies.
