This instalment describes several commonly used microextraction sample preparation techniques and their applications to forensic toxicology analysis. Solid-phase microextraction (SPME), microextraction by packed sorbent (MEPS), and different types of liquid-based microextraction (LPME), including single‑drop microextraction (SDME), hollow-fibre supported LPME, three-phase LPME, and dispersive liquid–liquid microextraction (DLLME), are discussed. Examples of application of these techniques to determine illicit drugs and drugs of abuse from various biological specimens are provided as well.
