Technologies to counter the proliferation of weapons of mass destructi
on by rogue governments and international terrorist organizations are
a top national priority. One of the top development requirements is fo
r highly sensitive and specific detection technologies for biological
warfare agents. This article describes the development of sensors for
field detection of weapons of mass destruction using an advanced time-
of-flight mass spectrometer system. This sensor system has the potenti
al to provide high speed, sensitivity, and specificity across a wide r
ange of biological agents, chemical agents, explosives, and contraband
materials. In addition, the system is being engineered to be rugged,
small, lightweight, and low power so that it can be deployable in the
field.
