Renishaw will exhibit its Streamline Plus fast Raman imaging systems at the 60th Pittsburgh conference on analytical chemistry and applied spectroscopy, from 8-13 March in Chicago.
Streamline Plus is a fully scalable Raman imaging system - it is possible to use readout times as short as 6ms per spectrum; a high-quality image of an entire tablet can be collected in less than four minutes.
The combination of line focus (which minimises sample damage), a high-speed encoded stage (HSES), 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, maximising adaptability and eliminating the need to stitch images together for large area coverage, resulting in artefact-free results.
The integration of the latest Wire 3.1 software with Streamline Plus offers numerous benefits to Raman users.
Regions of interest are simple to set up using optical micrograph montages; experiments can be queued, chemical images can be viewed and manipulated during acquisition, and a comprehensive suite of visualisation and chemometric tools is available to process and analyse the collected data.
The result is an intuitive workflow from sample loading to final reporting.
Wire 3.1 also offers a range of features including full support for multiple detectors, automatic spectrometer configuration for rapid hands-free excitation wavelength changes, and enhanced integration tools for third-party products (tandem systems).
Dr Nick Stone, from Gloucestershire Royal Hospital, routinely uses Streamline for screening biopsies, and says: 'To date, histological application of Raman mapping has been limited due to lengthy mapping times.
'Streamline Raman imaging is a mapping technique that has reduced total mapping times to a level that is becoming clinically practicable.' With Streamline Plus, a further two- to four-fold reduction in analysis time would be expected.
