The applications of ionic liquids (ILs) and IL‐derived sorbents are rapidly expanding. By
careful selection of the cation and anion components, the physicochemical properties of ILs …

In recent years, major attention has been focused on microextraction procedures that allow
high recovery of target analytes, regardless of the complexity of the sample matrices. The …

Extraction in the context of analytical chemistry (analytical-scale extraction) is defined as “the
transfer of target analyte from one phase to a different phase where further processing and …

Aiming towards simplifying sample preparation procedure, the present work explores use of
unmodified laboratory filter paper as sorbent for extraction of nine basic drugs (five …

Sample preparation is a critical step in forensic analytical toxicology. Different extraction
techniques are employed with the goals of removing interferences from the biological …

Benzodiazepines (BDZs) are used in clinics for anxiolysis, anticonvulsants, sedative
hypnosis, and muscle relaxation. They have high consumptions worldwide because of their …

The development of green sample preparation procedures is an extremely important
research field in which more and more applications are constantly being proposed in …

Benzodiazepines exhibit central nervous system depressive activity as well as sedative,
hypnotic, and anticonvulsant properties, which enable to use them as medical treatment in …

This study aims to prove that ionic liquids (ILs) can be used as extraction solvents in a liquid-
liquid microextraction, coupled to LC-MS/MS, for the quantification of a large group of …

In this article, a simple and efficient kind of homogeneous liquid-liquid microextraction based
on an acid–base reaction using switchable-hydrophilicity solvents was proposed for the …
