FBI's New Technology Revolutionizes DNA Analysis

From National Public Radio's Morning Edition, January 28, 2008:

"The newest wrinkle [in forensic DNA analysis] involves a rather innocuous-looking machine called a mass spectrometer, which is, in essence, a glorified scale that weighs individual molecules."

LCMS Finds Cocaine on Euros

This Analyst article on LCMS for the determination of drug contamination on Irish euro banknotes by Jonathan Bones, Mirek Macka and Brett Paull at the Dublin City University National Center for Sensor Research has been getting quite a bit of press. Trace cocaine was found on all 45 bank notes tested. This is perhaps not surprising, given the ease with which the powder is spread by ATMs and counting machines. Nonetheless, the authors report a significant sensitivity improvement in the LCMS method compared to previous GCMS studies.

Mass Spectrometry IDs Fake Fur

It isn't clear what test was performed, but this story about fake fur has been the biggest mass spectrometry item of the past week. One possibility is MALDI MS of keratin, as described in Identification and Quantification of Feathers, Down, and Hair of Avian and Mammalian Origin Using Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry by Klaus Hollemeyer, Wolfgang Altmeyer, and Elmar Heinzle, Anal. Chem.; 2002; 74 5960 (ht to Steve Down)
