Forgeries foiled: mass spec spots faked vehicle registratrions
Forgeries foiled: EASI mass spectrometry identifies falsified vehicle registration documents - Counterfeiting of legal documents, identity cards, passports and banknotes is an increasing problem worldwide, with an array of measures adopted by the forgers to try and dodge detection. The growing skill of forgers has led to the introduction of devices such as holographs, magnetic strips and watermarks to make it more difficult to produce convincing counterfeits. Inspection of suspect documents usually begins with visual examination, backed up by optical evaluation of image quality and finally by chemical and spectroscopic procedures. Many of these involve mass spectrometry in its various forms but a novel method has been introduced by a team of Brazilian researchers. They turned to one of the recently developed ambient mass spectrometry procedures involving easy ambient sonic spray ionisation (EASI) for the detection of falsified vehicle registration documents.
