| 1. A biological agent detection system comprising:
a pyrolyzer including a tube for collecting and processing a particle sample;
an inlet for fluid communication with the tube for drawing air containing the particle sample into the pyrolyzer;
a first outlet for fluid communication with an exhaust to exhaust the air from the pyrolyzer to atmosphere; and
a second outlet for fluid communication with a mass spectrometer, wherein gas molecules eluted from the particle sample collected
and processed in the tube are drawn into the mass spectrometer through the second outlet for identification.
