Explosives Residue Detection
Detection of low explosives
Using infusion based mass spectrometric methods and selective non-aqueous extraction techniques we are developing methods for the detection of fertilizer based explosives as ion-pairs. This mode of detection permits isolation of the explosives components in the presence of complex background matrices and interferences.
Detection of fertilizer based explosives
We utilize capillary ion analysis and electrospray mass spectrometry to isolate and detect pre and post blast components following the deflagration of low explosive devices. Using these techniques we can help determine the presence of oxidizers and fuels used in device manufacture. Simultaneous detection of anions and cations is also possible.
