Abstract

Analysis of bank security devices, containing 1-methylaminoanthraquinone (MAAQ) and o-chlorobenzylidenemalononitrile (CS), and pepper sprays, containing capsaicin, is a lengthy process with no specific screening technique to aid in identifying samples of interest. Direct Analysis in Real Time (DART) ionization coupled with an Accurate Time of Flight (AccuTOF) mass detector is a fast, ambient ionization source that could significantly reduce time spent on these cases and increase the specificity of the screening process. A new method for screening clothing for bank dye and pepper spray, using AccuTOF-DART analysis, has been developed. Detection of MAAQ, CS, and capsaicin was achieved via extraction of each compound onto cardstock paper, which was then sampled in the AccuTOF-DART. All results were verified using gas chromatography coupled with electron impact mass spectrometry.
