Fast, accurate detection of explosives on airport luggage possible

Abstract:
Fast, highly reliable detection of residues that could indicate the presence of explosives and other hazardous materials inside luggage is now possible with technology under development at Purdue University.

A research team led by R. Graham Cooks has found a way to determine the presence on a surface of trace quantities of chemicals – such as those found in biological and chemical warfare agents, as well as several common explosives – within a few seconds. The researchers' method uses a tool common in many chemistry and biology labs called a mass spectrometer that has been modified to analyze samples directly from the environment rather than requiring the lengthy pre-treatment that laboratory mass spectrometry samples typically require.
