The inVia InSpect can identify materials that may be difficult or time consuming to prepare.

Renishaw recently launched the inVia™ InSpect, a new version of its bestselling inVia confocal Raman microscope, optimised for use in forensic laboratories for trace chemical analysis. The inVia InSpect can identify materials that may be difficult or time consuming to prepare. For example, hard crystalline powders, ceramic shards and glass chips can all be easily analysed with no preparation required. InSpect also offers a powerful confocal Raman capability, providing pinpoint analysis without interference from surrounding adjacent materials – vital for analysing complex structures containing layers, voids or inclusions. Dr Chris Dyer, Product Manager for Chemical and Forensic Sciences at Renishaw plc, said “We have spoken with staff at forensics laboratories worldwide and identified a need for a highly sensitive Raman microscope that can process samples that are currently not compatible with more commonly used microscopy systems…

“Renishaw's inVia Raman microscope is one of the best on the market, renowned for its ultra-sensitivity and overall efficiency. We have honed it and added features to optimise it for use in the majority of forensic laboratories. Users will be able to process more samples, more rapidly; even those which are usually difficult or time consuming to analyse. Furthermore, samples will retain their integrity as minimal preparation is required. And users who are unfamiliar with Raman will find the InSpect simple to learn and easy to use.”

Raman spectroscopy is a non-contact, typically non-destructive analytical technique, meaning that samples can be reanalysed multiple times without damage or contamination. There is typically very little, or no sample preparation needed. Raman spectroscopy also works through transparent containers and in solution, so samples that are potentially dangerous or require special handling can be safely examined.
