In recent years, arson using alternative ignitable liquids such as lighter fluid have been occurring. Detector tubes utilized as on-site detection methods in Japan are specialized for gasoline and kerosene. We investigated the effectiveness of commercially available flammable gas detectors as an alternative to these methods.

Performance of the portable stand-off Raman spectroscopic analyzer Pendar X10 was evaluated. Various chemical warfare agents could be detected correctly and remotely. In addition, substances that could be mistaken for suspicious objects were also analyzed, and most of them were detected correctly. It was also possible to detect chemicals through umber colored bottles and paper envelopes, which are difficult to detect with the traditional Raman spectroscopic analyzers. Stand-off measurement up to 2 m and operability while wearing Level A chemical protective clothing was also verified.
