“…The main factors affecting the extraction such as type of salt and its amount, type of organic solvent, vortex and centrifuge times were investigated. Acetonitrile is the most widely used solvent for SALLE [20] and has many attractive properties such as the good miscibility with water, its favourable polarity that facilitates the extraction of a wide range of compounds and furthermore, can be directly injected to GC instruments. Acetonitrile is also less harmful to the environment compared to the other common liquid extraction solvents.…”

“…54 A more convenient way to achieve phase separation between an aqueous sample and a water-miscible solvent is salt-assisted liquid-liquid extraction (SALLE), where the polarity of the aqueous phase is increased by adding high concentration of salt, leading to phase separation. 55 This approach has been used for quantitation of pharmaceutical compounds from biouids using LC 56 or LC-MS/MS. [57][58][59] Novel sample preparation methods Many common interferents can be removed with conventional sample preparation methods (e.g.…”
Liquid chromatography-mass spectrometry analysis of small molecules from biofluids requires sensitive and robust assays. Because of the very complex nature of many biological samples, efficient sample preparation protocols to remove unwanted components and to selectively extract the compounds of interest are an essential part of almost every bioanalytical workflow. This review describes the most common problems encountered during sample preparation, ways to optimize established sample preparation techniques and important recent developments to reduce or eliminate major interferents from biofluids.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
