Abstract
The Block II Chemical Biological Mass Spectrometer (CBMS) detects and identifies both chemical and biological warfare agents. Biodetection is based upon respirable particle collection by an opposed-jet virtual impactor, liberation of derivatized biomarkers by thermolysis-methylation and their analysis by direct-sampling ion trap mass spectrometry in the full-scan chemical ionization mode. Results from laboratory and field trials demonstrate the capability of the Block II CBMS for biodetection and identification.
