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.
A report on the 12th Confocal Raman Imaging Symposium held in Ulm, Germany, September 2015, which covered a fascinating range of applications of the technique.
Using Raman spectroscopy and statistical analysis, an international group of scientists has succeeded in taking nanoscale measurements of the strain present at each pixel on the surface of graphene. The researchers also obtained a high-resolution view of the chemical properties of the graphene surface.
Kidney stones rank among the most common illnesses. Their recurrence may be prevented with the right post-operative care. However, for this to be effective, the composition of the stones needs to be known. Fraunhofer researchers are developing a Raman spectroscopy based system for rapid analysis of urinary stones immediately after the surgical procedure.
The new and improved S11850-1106 and S11851-1106 back-thinned CCD linear image sensors from Hamamatsu Photonics have improved etaloning characteristics and high sensitivity designed for spectrometry applications.
Horiba Scientific and AIST-NT now offer a solution that addresses the instrumentation concerns of tip enhanced Raman scattering (TERS).
Graphene has been receiving a large amount of interest as its commercial possibilities begin to be realised. Now, with hundreds of companies offering commercial graphene production, analytical measures of graphene quality are required. Raman spectroscopy can be used to “understand the number of layers, strain, doping and importantly the level of disorder present in graphene”, which is described in this article: “Graphene characterisation and standardisation via Raman spectroscopy” by Andrew Pollard and Debdulal Roy.
The National Physical Laboratory (NPL) in the UK has used tip-enhanced Raman spectroscopy to map catalytic reactions at the nanoscale for the first time.
Tornado Spectral Systems has released the HyperFlux P.R.O. Plus process Raman analyser
Automated detection of counterfeit drugs using multimodal spectroscopy and advanced web-based software platforms
In the Tony Davies Column, we learn about “Automated detection of counterfeit drugs using multimodal spectroscopy and advanced web-based software platforms”. With the increase in trafficking of counterfeit medicines and other products, there is a need for definitive results from an on-site analyser useable by customs officers. The German authorities have commissioned the development of a multi-modal, transportable inspection system, including intelligent data processing and evaluation, for fast spectroscopic recognition of illicit drugs and counterfeit medicines. This is described in the column.
Raman microscopy is being used alongside high-resolution X-ray diffraction to unpick the reasons for crystallographic defects in SiC bulk crystal and epitaxial film, which limit the commercialisation of SiC devices.
Canadian researchers have used SERS to screen blood samples for molecular traces that indicate the presence of precancerous polyps in the colon, a key warning sign for colon cancer. Their results may yield a cheaper and less invasive initial screening test for colon cancer that could complement colonoscopy, though further clinical trials will need to demonstrate the safety and effectiveness of the blood test before it is routinely used.
