Development of a novel seized drug screening method utilizing DART-MS and used weigh paper
AN Couch, JT Davidson - Forensic Chemistry, 2024 - Elsevier
The conventional analytical scheme for seized drug analysis utilizes quick and cost-effective
presumptive testing, such as color tests, followed by more discriminatory techniques, such
as gas chromatography-mass spectrometry (GC–MS). Before the seized drug evidence is
analyzed, the evidence is weighed using an appropriate weighing matrix and balance.
Typically, the weighing matrix is discarded as chemical waste; however, the process of
weighing the evidence leads to the deposition of drug residue onto the weighing matrix …
