“…Bar adsorptive microextraction (BAµE) was recently introduced [37] and offers to the operator the possibility to choose the most convenient sorbent phase (polymers or ACs), according to the chemical characteristics of the target analytes [36]. This analytical approach is an alternative by simplification, miniaturization and high-throughput to enhance selectivity and sensitivity, in particular for trace analysis.…”

“…This analytical approach is an alternative by simplification, miniaturization and high-throughput to enhance selectivity and sensitivity, in particular for trace analysis. Furthermore, this new technique uses negligible amount of solvents and low sample volumes [36].This enrichment technique simultaneously combines microextraction and concentration of the analytes, operating under the floating sampling technology, in a one single step. On the other hand, reduces handling, the overall time required for sample preparation and is suitable to be combined with the high sensitivity of modern analytical instrumentation.…”

“…In the last decades, new microextraction techniques have emerged, namely solid-phase microextraction and stir bar sorptive extraction, since they use negligible amount of solvent, low sample volume and simplified approach [36]. However, these techniques use a small number of polymeric materials (e.g., polydimethylsiloxane) as sorbents and the coating with ACs is still little explored.…”

The application of monolithic material sorption extraction, specifi cally MonoTrap TM , to the extraction of organic gunshot residue (OGSR) compounds from unburnt propellant powders is described. Four different MonoTraps were assessed for their capability to extract OGSR compounds from two different ammunition types. Extracts were analysed using gas chromatography-mass spectrometry. Results indicated that the carbon disc was suitable for the extraction of OGSR compounds from unburnt propellant powders. Quantities for major compounds were comparable to methanol extractions. The method was successfully used to detect a wide range of OGSR compounds, including nitrotoluenes, nitroglycerin, diphenylamines and centralites and is expected to be applicable to a wide range of ammunition types.

The global concern about food safety and environment quality has produced the development of a legal framework to control residues of organic compounds (e.g. pesticides and veterinary and human drugs). In this context, the establishment of analytical methods achieving satisfactory performances in terms of sensitivity, selectivity, resolution, identification, sample throughput, and applicability, is mandatory. Multiresidue methods mainly based on chromatographic techniques [i.e., gas chromatography (GC) and liquid chromatography (LC)] coupled to mass spectrometry (MS) are currently applied in routine laboratories. Furthermore, capillary electrophoresis (CE) has emerged as an alternative to LC and GC, owing to the development of on‐line preconcentration strategies for sensitivity enhancement. The recent integration of ion mobility spectrometry (IMS) in LC‐MS workflows also involves new possibilities for the separation of isomeric and isobaric residues, as well as for the separation of analytes of interest from background noise. New trends in multiresidue analysis point towards ambient ionization mass spectrometry (AIMS) strategies, which avoid chromatographic separations and substantially reduce analysis time. On the other hand, sample preparation has evolved through the development of miniaturized and environmentally friendly procedures according to the Green Chemistry principles. In addition, generic extraction procedures for multiclass analysis have been optimized, increasing sample throughput. This article aims to show an overview of the current trends in the analysis of pesticide and drugs in food and environmental samples, discussing the relevant advances in sample treatments and the technological evolution of the instrumental techniques. We hope to offer with this article a critical review of the analytical possibilities for routine analysis laboratories focused on monitoring of residues.
