Complementary Technique

The Renishaw InVia InSpect Raman microscope complements the wide range of analytical systems and microscopes in the forensic lab. It can be used alone to analyse samples that cannot be examined fully using other techniques, or it can also be used together with other microscopic imaging techniques to provide more detailed chemical information about the evidence.

Why use Raman?

The inVia InSpect can identify materials that would be difficult or time consuming to analyse using other methods. For example, hard crystalline powders, ceramic shards and glass chips can all be analysed easily without preparation.

The powerful confocal Raman capabilities deliver pinpoint analysis without interference from surrounding materials. This is important for analysing complex structures containing layers, voids or inclusions.

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.

Ideal for Forensics

Raman spectroscopy is a non-contact and typically non-destructive analytical technique. This enables you to analyse evidence multiple times without damage or contamination.

Little or no sample preparation is required, making it a quick and convenient technique to use.

Raman spectroscopy also works through transparent containers and in solution, so samples that are potentially dangerous or require special handling can be examined safely and without contamination.
