Solution Overview

Problem

Current methods are inadequate for releasing both organic and inorganic explosive materials from a carrier medium, particularly inorganic salt-based explosives with high boiling points, which are not effectively vaporized by traditional thermal techniques.

Innovation Solution

Treatment of the sample with a first organic reagent that binds to the cation of an inorganic salt to produce a volatile compound and an isolated anion, followed by treatment with a second organic reagent that reacts with the anion to produce another volatile compound, allowing for the release of these compounds from the carrier medium, either simultaneously or at different times, using techniques such as reducing pressure or heating.
