Tests show LLNL detection instrument can monitor the air for all major terrorist threat substances
Date:8/10/2008

lion particles studied, there were so few that no alarms would have been triggered.

"What distinguishes SPAMS from other instruments is the high-quality information we receive from the instrument in the form of single-particle mass spectra," Frank said. "As a result, we get specificity and many fewer false alarms. We're very enthusiastic about how the system is working, not only in the lab but also in field tests."

For the future, the Livermore team would like to develop ways to make the SPAMS machine smaller and less expensive.

They would like to find opportunities for additional field tests, such as at airports, where SPAMS could be used to screen checked and carry-on baggage and at passenger portals. The instrument also could assist in screening people for disease and might help law enforcement authorities in examining suspicious powder samples.
