High-profile courts cases—from securities fraud to murder investigations—often hinge upon suspicious documents, requiring comparison between inks or reference databases. Counterfeit currency detection also relies upon analysis of the inks as well as the paper itself. Speed and accuracy are essential in building cases and making them stick. Thermo Fisher Scientific offers peer-proven paper and ink investigation tools to assist Forensic Document Examiners view suspicious articles regarding theft identity, forgery, counterfeiting, fraud, or uttering of a forged document.
The Thermo Scientific tools comply with published forensic sciences standards from the American Society for Testing and Materials (ASTM) International for methods and procedures recommending the use of UV-VIS and FTIR spectroscopy. The ASTM Subcommittee E30.90 publishes a variety of such standards detailing methods and specific test types related to ink and paper testing for FDEs.
Inks may also be distinguished by other more complex chemical tests like chromatography, mass spectrometry, and other techniques but these are likely to be destructive to some extent. Access to the power of mass spectrometry provides your laboratory with additional options to confirm initial findings.
In this eBook overview of the current state of forensic chemistry and the latest mass spectrometry technology for staying ahead of your casework, we discuss:
Solve analytical challenges using the Nicolet iS50 FT-IR Spectrometer, featuring purpose-built accessories and integrated software.
In our latest application handbook, we provide access to clinical research and forensic drug chemistry applications, peer reviewed references and recent technical posters for a wide range of experimental techniques, including mass spectrometry (including single quadrupole, triple quadrupole and quantitative high resolution systems), liquid chromatography and a variety of sample prep solutions.
