The Purdue miniature mass spectrometer can easily be carried with one hand.

Researchers at Purdue University have created a miniature mass spectrometer that promises to have applications in everything from airport security to medical diagnostics. This latest prototype, the Mini 10 portable mass spectrometer, is roughly the size of a shoebox and can easily be carried with one hand. The instrument is 13.5 inches long, 8.5 inches wide and 7.5 inches tall. It weighs 22 pounds. A conventional mass spectrometer was about 30 times that. The mini can also run on batteries.

DESI technology can perform a molecular scan of any open surface, such as this backpack.

Doctoral student Christopher Mulligan uses a desorption electrospray ionization (DESI) tube to scan the outside of a backpack worn by Adam Keil, a postdoctoral research associate. The spray knocks molecules off the pack's surface, which and are then analyzed by the Mini 10 portable spectrometer, a shoebox-size instrument about 30 times lighter than conventional mass spectrometers. The mini can also run on batteries.
