Manufactured by CDI Pharma, the Shakti “process ready” Raman analyser system features a high- resolution, wide spectral range, high sensitivity and auto-calibration spectrometer with a built-in self-referencing probe, adjustable working distance and adjustable sample spot size. Applications include raw material ID, coating content, polymorph screening, measuring drug concentration in dissolution media, quantitating solid phase transformations in situ and analysing solid-phase transformations during fluidised bed drying.CDI Pharma Issue: 21/01 RSN: 123
Renishaw has developed its Streamline Plus Raman imaging system, which combines hardware, software and firmware to improve data collection, visualisation and processing. The combination of line focus, for minimal sample damage, high-speed encoded stage and synchronised readout of the CCD detector enables images to be collected rapidly and at variable spatial resolution. There are no limits to the image area dimensions imposed by the objective field of view, therefore enabling adaptability and eliminating the need to stitch images together for large area coverage, resulting in artefact-free results. Integration of WiRE 3.1 software offers many benefits. Regions of interest are simple to set up using optical micrograph montages, experiments can be queued and chemical images can be viewed and manipulated during acquisition, whilst a suite of visualisation and chemometric tools are available to process and analyse the collected data. The software also offers additional features including full support for multiple detectors, automatic spectrometer configuration for “hands-free” excitation wavelength changes and enhanced integration tools for third party products.Renishaw Plc Issue: 21/01 RSN: 122
Scientists at the University of Edinburgh, UK, have developed a technique using Raman spectroscopy to test the quality of sperm before it is used for in vitro fertilisation (IVF) and increase the chances of conception. Dr Alastair Elfick, lead scientist on the project, explained: “in natural conception the fittest and healthiest sperm are positively selected by the arduous journey they make to the egg. What our technology does is to replace natural selection with a DNA-based ‘quality score’.” This can then be used to decide whether the sperm is healthy enough to be used to fertilise an egg as part of the IVF treatment.
The sperm are captured in two highly focussed beams of laser light, optical tweezers, and then the DNA of an individual sperm can be analysed from its Raman spectrum. The research is currently in a pre-clinical phase, and if successful could be available to patients in the next five to ten years.
Researchers at the Humboldt-Universität zu Berlin, Germany, have reported in Analytical Chemistry (doi: 10.1021/ac801791a) an advance toward development of technology that could underpin automated, real-time systems for identifying specific kinds of plant pollen circulating in the air.

Janina Kneipp and colleagues explain that current pollen counts and allergy warnings are based on visual identification of the specific kind of pollen by examining pollen grains under a microscope. That procedure takes time, making it impossible for allergy-sufferers to know the kinds of pollen that are airborne on an hour-by-hour basis. The researchers describe using Raman spectroscopy to identify chemical structures in pollen grains that distinguish oak and maple pollen, for instance, from maple and other kinds. They obtained these chemical “signatures” for 15 different kinds of tree pollen.

Renishaw have unveiled their new Raman imaging system, the Streamline Plus Raman system. A development of this new system is its increase in speed due to optimisation of the software, detector hardware and the use of the company's new MS10 high-speed microscope stage, making it possible to collect spatially resolved chemical information from samples as large and complex as whole pharmaceutical tablets in a short space of time. The mapping also works well on biological cells and inorganic surfaces.Renishaw PlcIssue: 20/05 RSN:

According to the World Health Organisation (WHO), a counterfeit drug is one that is deliberately and fraudulently mislabelled with respect to identity and/or source. Counterfeiting can apply to both branded and generic products; counterfeit products may include products with correct or wrong ingredients, without active ingredients, with insufficient active ingredient or fake packaging.
RSP Systems has launched a new type of Raman spectrometer, mySpec Integrated, which enables the rejection of fluorescence in the spectra and increases reproducibility. This is made possible by using a double slit system in a fixed set-up. It also provides advanced chemometric possibilities due to the added data obtained. The system consists of a 532 nm laser, TE cooled CCD, 8 cm–:1 resolution, all fitted into a device measuring 300 × 185 × 85 mm. It is suitable for process control applications, in the laboratory and at/in line.RSP Systems ASIssue: 20/03 RSN:
asco has released its new RMP-300 Series portable Raman spectrometer systems. The instruments feature an integrated fibre-optic probe with a small X-Y-Z stage, a compact laser, a high-throughput spectrograph and CCD detector. No special utilities such as coolants are required, allowing the systems to be used almost anywhere. The flexibility of the optical fibre coupling enables remote measurements by locating the probe right at the sample. The fibre-optic probe features an integrated CCD camera for sample positioning and capture of digital sample images. The series consists of six models, ranging from small, portable units suitable for in situ measurements to research-grade systems that will meet most difficult application requirements. System operations are controlled by the Spectra Manager II windows-based cross-platform spectroscopy software package and are powerful enough for both laboratory work and on-site measurements in the fields of process control, QC, forensics, art conservation and mineralogy.Jasco Europe srlIssue: 20/03 RSN:
Scientists at the Science and Technology Facilities Council (STFC) Rutherford Appleton Laboratory in Oxfordshire, UK, have developed an effective laser-based method for the non-destructive characterisation of the bulk chemical content of pharmaceutical capsules. In collaboration with Pfizer Ltd, the researchers in STFC's Lasers for Science Facility succeeded in quantifying the presence of the active pharmaceutical ingredient in production line relevant capsules to a relative error of 1%. Other established non-invasive methods were unable to reach the same level of accuracy with the same sample.
The technique holds great potential for a range of process control applications in the pharmaceutical industry. The results of the collaborative study are reported in the J. Pharm. Biomed. Anal. (doi: 10.1016/j.jpba.2008.01.013). The development stems from research into Spatially Offset Raman Spectroscopy, which is under development at STFC for a wide range of applications including the detection of explosives in non-metallic containers, the detection of counterfeit drugs through opaque packaging and the non-invasive diagnosis of bone disease and cancer [see Spectrosc. Europe 19(5), 7 (2007)]. The concepts, which are relatively simple to implement, were developed through experiments involving STFC's large scale facilities which provided crucial insight into photon transport processes.
The development is being carried out with STFC's knowledge technology transfer arm and the new techniques are planned for commercialisation through STFC's spin-out company LiteThru Ltd.
