Sniffing out a broad-spectrum of airborne threats in seconds

Scientists in California are reporting successful laboratory and field tests of a new device that can sniff out the faintest traces of a wide range of chemical, biological, nuclear, and explosive threats - and illicit drugs - from the air in minutes with great accuracy. The ultra-sensitive detector, known as the single-particle aerosol mass spectrometry (SPAMS) system, could tighten security at airports, sports stadiums and other large-scale facilities, according to their report, scheduled for the July 1 issue of ACS' Analytical Chemistry.
