In a recent study led by Bob Pirok and Rick S. van den Hurk of the Van ’t Hoff Institute for Molecular Sciences at the University of Amsterdam a novel heart-cutting two-dimensional liquid chromatography (2D-LC) workflow capable of simultaneously separating and detecting both inorganic and organic explosive residues from a single injection was developed (1). This latest innovation has implications for post-blast forensic analysis.
