Proven Proprietary Provenance Technology 

​

TSW Trace TM is a robust, definitive, tested and validated scientific method for establishing provenance of an item. Advanced scientific instrumentation is used to determine key markers (elements, isotopes and molecules present), which when combined form a chemical 'fingerprint' or 'profile' that is characteristic of an items' origin. 

​

Pioneered by TSW's Chief Scientist Dr R. John Watling, the technology brings together almost 40 years of research and application across various disciplines. The method is routinely employed as a forensic tool and delivered by the TSW Analytical Pty Ltd Forensic Science Services team who, combined, have over 60 years of advanced research and forensic casework experience and are world leaders in the provenance establishment. ​The TSW team has published extensively. In addition to more than 100 peer-reviewed publications, the applications have been presented at scientific conferences worldwide, form the basis of book chapters and feature in the internationally referenced forensic treatises for Expert Evidence - 'Gold Fingerprinting' and '75 Expert Areas'.

This technology can be applied to almost every solid or liquid matrices and has been used for:
