Abstract
Methods, devices, and systems are disclosed for releasing a sample from a carrier medium. A method of releasing a sample from a carrier medium comprises treating a sample on a carrier medium with a first organic reagent, wherein when the sample contains at least one inorganic salt, the first organic reagent binds to a cation of the inorganic salt to produce both a first volatile compound and an isolated anion of the inorganic salt; treating the sample on the carrier medium with a second organic reagent, wherein the second organic reagent reacts with the isolated anion to produce a second volatile compound; and releasing the treated sample from the carrier medium, wherein when the first and the second volatile compounds are produced, the releasing step releases at least one of the first and second volatile compounds from the carrier medium.
