Jasco’s NRS-5000/7000 series of Raman spectrometers can integrate as many as eight excitation lasers (nine wavelengths) from the UV to the NIR, with automated laser/Raman scattering path alignment, automated grating and laser selection and up to two detectors. The NRS-5100/5200 instruments feature a 300 mm spectrograph and three selectable gratings. The NRS-7100/7200 instruments include a 500 mm spectrograph and up to four selectable gratings. The NRS-5200 and NRS-7200 instruments offer a dual-grating, low wavenumber measurement unit for optimised Raleigh rejection and Raman spectra down to 10 cm–1. The NRS-5000/7000 instruments offer high-speed imaging capability using the Software Programmable Raman Integration System (SPRIntS) for rapid scanning and sample imaging capabilities. The Verti-Scan capability ensures a consistent confocal sample excitation capability to obtain undistorted 3D images, without the use of an automated X-Y-Z sample stage. The Dual Spatial Filtering capability reduces sample fluorescence while enhancing spatial resolution.
Ahura Scientific, Inc., has announced the close of Thermo Fisher Scientific Inc.’s acquisition of the company. The acquisition expands Thermo Fisher’s technology portfolio with a suite ofportable spectrometers.
Ahura Scientific, now part of Thermo Fisher Scientific, have introduced the FirstDefender RM and FirstDefender RMX, rugged handheld Raman spectrometers for use by first responders, homeland security, military, law enforcement and forensic chemistry personnel. The instruments allow users to quickly identify unknown chemicals from a vast sample library of more than 10,000 pure substances including: explosives, toxic industrial chemicals (TICs), toxic industrial materials (TIMs), chemical warfare agents (CWAs), white powders, narcotics, precursors and more. Ahura Scientific’s chemometric algorithms enable automatic mixture analysis with every scan. Both instruments are certified to US military’s MIL-STD 810F specifications for ruggedness including drop, shock, vibration and operation in extreme temperatures.
Thermo Fisher Scientific has signed a definitive agreement to acquire Ahura Scientific, manufacturer of portable spectrometers, for $145 million in cash plus the potential for an earn-out payment based on the achievement of certain 2010 financial targets. The acquisition expands Thermo’s portfolio of portable instruments; they already have a line of portable XRF analysers. www.thermofisher.com, www.ahurascientific.com
Sword Diagnostics has been awarded a US Patent titled Method and Apparatus for Detection of Biological Organisms using Raman Scattering. The patent covers the core technology which focuses on improved sensitivity. www.sworddiagnostics.com
Horiba has announced the construction of a new research facility and European headquarters on the campus of the École Polytechnique in Paris. The new centre will give Horiba access to a pool of innovative technologies, resources and personnel from nearby academic, government and commercial research centres. It is due to open in late 2011. www.horiba.com/uk/scientific
ChemImage has been selected for $2 million of US defence funding for further development of the Eye-Safe Stand-Off Fusion Detection of chemical, biological, explosive and improvised explosive device threats. The system will combine multiple sensing technologies, including Raman and shortwave infrared chemical imaging. www.chemimage.com
Newport Corporation has introduced a new coherent anti-Stokes Raman scattering optimised supercontinuum generation fibre device, the SCG-800-CARS, which has been designed for use with 800 nm femtosecond lasers and contains 12 cm non-linear crystal fibre with zero dispersion points at ~775 nm and 945 nm.
Researchers at the University of St Andrews have developed a powerful technique that could allow earlier cancer detection. In a joint venture between the Schools of Physics & Astronomy and the Bute Medical School, the St Andrews researchers have advanced new technology that relies on Raman spectroscopy.
The winners of the 2010 Pittcon Awards include a good number of spectroscopists, and names that will be familiar to readers.
Smiths Detection has received a $21.9 million order from the US Transportation Security Administration to supply its Raman spectroscopy-based portable liquid detection scanners to analyse the content of containers without opening them. www.smithsdetection.com
Bruker has announced the launch of its N8 Neos Santerra micro analysis system that combines Raman spectroscopy and atomic force microscopy on a single optical microscope platform.
The judicious use of a state-of-the-art imaging method enables researchers to capture structural snapshots of complex molecules as they participate in chemical reactions, revealing the sequence of specific atomic motions that lead to chemical change. It’s thought the approach, described in Nature (doi: 10.1038/nature08527), can be used more widely to improve our understanding of important chemical transformations.
Scientists at Queen’s University Belfast are developing a Raman spectroscopy-based sensor to detect chemical agents and illegal drugs which will help in the fight against the threat of terrorist attacks. Special gel pads will be used to “swipe” an individual or crime scene to gather a sample which is then analysed by the Raman instrument that can detect the presence of chemicals within seconds. This will allow better, faster decisions to be made in response to terrorist threats.
Princeton Instruments has introduced an intensified CCD camera, the PI-Max 3. It is a fully integrated camera that provides a combination of frame rate, gating and low-noise capabilities for improved performance in applications such as fluorescence lifetime imaging measurements, laser-induced breakdown spectroscopy, pulsed Raman spectroscopy, nanotechnology studies and plasma diagnostics. Features include a built-in timing generator, the SuperSynchro, which makes setting up complex time-resolved imaging experiments easy, SyncMaster technology helps reduce lab clutter by eliminating the need for an external timing generator, it can be configured with either a 1024 × 1024-pixel interline transfer CCD or a 1024 × 246-pixel full-frame CCD and it also features photocathode cooling for ultra-low light or single-photon imaging as well as special readout modes for single-shot measurements and particle imaging velocimetry applications.Princeton Instruments Acton Issue: 21/05 RSN: 112 More information via
ST Japan have added 2100 new Raman spectra to their existing collection and now offer more than 10,000 spectra, including polymers and additives, solvents, pharmaceuticals, packaging materials, forensics and minerals. All spectra have been taken from samples of high purity, contain extensive sample information and have been reviewed by trained spectroscopists. The databases are available in the common spectra format and can be used directly with the search software of the users instrument, enabling them to continue working in their usual software environment and improve search results.S T Japan-Europe Issue: 21/05 RSN: 121 More information via
Ahura Scientific has announced an upgrade to the language capabilities of its TruScan hand-held Raman spectrometer, designed for the pharmaceutical and consumer health industries. With the introduction of TruScan 1.3.0, the graphical user interface is accessible in German as are the user manuals and instrument administration tools.Ahura Scientific Issue: 21/05 RSN: 120 More information via
The new DSC-Raman system from PerkinElmer combines thermal analysis with Raman spectroscopy to provide greater insight into material changes at a molecular level. It combines the double furnace DSC 8500 with the RamanStation 400 spectrometer, enabling simultaneous analysis of chemical and structural information from the spectrometer and correlating it with the calorimetric data of the DSC. Tests using the hyphenated techniques have given greater insight into polymer crystallisation, drug–carrier interactions, curing and polymorphic changes.
