Renishaw will present solutions to challenging forensic problems at the upcoming European Academy of Forensic Science conference in Glasgow.
Streamline Plus imaging can be used to tackle previously difficult and time-consuming issues such as the non-destructive composition analysis of suspected illegal narcotic tablets and crossing ink lines sequencing on questioned documents.
The small sampling volume and high chemical sensitivity afforded by this novel Raman method quickly address such challenging requirements.
Blind trials indicate that Renishaw Streamline Plus imaging is three times more successful than traditional techniques in determining the deposition order of crossing ink lines.
Unambiguous chemical characterisation is coupled with minimal sample preparation, contact-free laser interaction and speedy analysis, to provide a complete solution for ink analysis.
Streamline Plus can be applied with equal success to printer inks.
It can overcome many forensic challenges for which identification of micro-contaminants over large areas is fundamentally important, such as: explosives detection on fabrics; analysis of narcotic micro-particles in fingerprints; and investigating the chemical composition of unknown tablets.
In addition to being adopted by many forensic institutions, unequivocal Raman data have contributed to the outcome of high-profile fraud cases.
Streamline Plus is supplementing or replacing more established methods such as infrared analysis.
The easy-to-understand images produced by Streamline Plus enable results to be presented and interpreted by non-experts, which is vital in court cases.
By determining chemical components, Streamline Plus can identify MDMA (ecstasy) tablets without the need for sample preparation.
