Spatially Offset Raman Spectroscopy (SORS)
Spatially Offset Raman Spectroscopy, is a novel method for accurate and robust chemical analysis of objects where the contents are obscured by an opaque layer or container.
There are many applications of SORS for subsurface analysis and some of these are discussed in our Downloads section. Applications include:
- Screening containers for explosives detection in security checks
- Biomedical screening and tissue analysis
- Counterfeit detection of pharmaceutical products
The method requires no prior knowledge of the container/surface layer, does not require physically touching or changing the object and can probe to depths of many millimetres. Cobalt develops instruments using proprietary SORS technology, including the Insight100 range of bottle screeners for liquid explosives detection and the RapID system for pharmaceutical raw materials identification.
