Introduction

Interest in Raman spectroscopy as an analytical technique that can be applied in a wide variety of fields continues to increase. The main reason for this interest is that no special sample preparation is required. However, the Raman signal is typically very weak, with only one in every 106–108 photons being scattered. This has driven the development of several enhancement techniques, e.g. Resonance Raman (RR), Surface Enhanced Raman Spectroscopy (SERS) and Surface Enhanced Resonance Raman Spectroscopy (SERRS), which can be used for dilute samples.

The development of the Raman imaging spectrograph came from the need for combining high light throughput, distortion-free performance and polarisation-free optical design. These requirements, together with the small footprint of the device, good image quality and high spectral resolution were achieved with the fully transmissive design used in the Specim ImSpector series of imaging spectrographs, which are available for several standard wavelength ranges from 500 nm up to 1000 nm for use with different types of excitation lasers.

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.

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.

Scientists have identified chemical structures in pollen, shown covering the face and legs of a Marmelade fly, that could help provide a real-time pollen detection and warning system to help allergy sufferers. Credit: André Karwath

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.

Introduction

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:
