TL;DR: The chromatographic behavior of ephedrines on a C18 column was studied with different concentrations of 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquids as the eluent at pH 3.0.

TL;DR: Results showed that this new anion-exchange phase based on N-methylimidazolium immobilized on silica can be used in the analysis of these in organic anions with great prospects.

TL;DR: Results show that the new stationary phase is of significant potential for the analysis of common inorganic anions and can be determined simultaneously and satisfactorily with several neutral compounds using the column.

TL;DR: A novel solid-phase microextraction fiber based on a stainless steel wire coated with Au nanoparticles was prepared and has been applied, coupled with gas chromatography, to the extraction of aromatic hydrophobic organic chemical pollutants in rainwater and soil extract, exhibiting excellent extraction efficiency and selectivity.

TL;DR: This review focused on the development of silica-based stationary phases, including the synthesis ofsilica gel and the application of silicas in hydrophilic interaction chromatography, reversed-phase liquid chromatography (RPLC), chiral separation Chromatography, and ion chromatography.
