In recent years, the interest in new extraction methods with lower sample volume
requirements, simpler equipment and handling, and lower reagent consumption, has led to …

The use of membrane-based sample preparation techniques in analytical chemistry has
gained growing attention from the scientific community since the development of …

Sample preparation is an important issue in analytical chemistry, and is often a bottleneck in
chemical analysis. So, the major incentive for the recent research has been to attain faster …

The current study presents for the first time a combination of the gel electromembrane
extraction (GEL-EME) and switchable hydrophilicity solvent-based homogeneous liquid …

For the first time, we report electromembrane extraction (EME) of peptides using deep
eutectic solvent (DES) as supported liquid membrane (SLM). DES were mixtures of …

Conductive vial electromembrane extraction (EME) with prototype equipment was applied
for the first time to extract lipophilic basic drugs from serum. With this equipment, traditional …

Tryptamines are a class of new psychoactive substances relevant for analysis in forensic
laboratories. Tryptamine analogs are diverse in structure and chemical properties, and …

This study proposes the dual electromembrane extraction followed by high performance
liquid chromatography for selective separation-preconcentration of Cr (VI) and Cr (III) in …

Over the past three decades, many studies employing hollow-fiber liquid-phase
microextraction (HF-LPME) bioanalytical methods have been published. The basic …

The use of a new class of hybrid materials, called restricted access molecularly imprinted
polymers (RAMIPs) seems to present a good strategy for the sample preparation of complex …
