Enantioselective Determination of Amphetamine‐Type Stimulants in Environmental Waters Using SPE and CE–MS/MS

ELECTROPHORESIS, Volume 47, Issue 3, Page 250-260, March 2026.
ABSTRACT The growing concern over drug abuse, particularly involving amphetamine‐type substances (ATS), has led to their monitoring in environmental waters. These chiral compounds, commonly found in river water and wastewater treatment plant (WWTP) effluents, require analytical methods capable of enantiomeric discrimination, as their enantiomers can ...

The hexane-ethyl acetate-methanol-water system for the separation of theaflavins from black tea (Camellia sinensis) using high-speed counter-current chromatography

Ceylon Journal of Science, 2016
Theaflavins (TFs) from black tea leaves were separated using high-speed countercurrent chromatography (HSCCC). Isobutyl methyl ketone (4-methyl-2-pentanone) was used to separate the TFs from a hot water extract of black tea leaves.

Seasonal Variation of Off‐Flavours in a Full‐Scale Recirculating Aquaculture System Rearing Rainbow Trout Oncorhynchus mykiss—A Case Study

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Recirculating aquaculture system (RAS) is a promising strategy for economically and environmentally sustainable fish farming. Unfortunately, microorganisms in an RAS may produce off‐flavours that accumulate in fish flesh and reduce consumer attraction for aquaculture‐produced fish. Traditionally, geosmin (GSM) and 2‐methylisoborneol (MIB), the
