"Scientists in California and Michigan report development toward a "universal point detection system," a long sought three-in-one machine that screens airline passengers and baggage for explosive, chemical and biological threats at the same time. George R. Farquar and colleagues describe latest tests on the device, which uses a technology called single-particle aerosol mass spectrometry (SPAMS), in an article ""Identification of High Explosives Using Single-Particle Aerosol Mass Spectrometry" scheduled for the March 15 issue of the ACS' Analytical Chemistry, a semi-monthly journal."
