摘要:Major obstacles to formulating a simple retention mechanism for reversed-phase liquid chromatography are identified as the heterogeneous composition of the stationary phase, the difficulty of providing a working definition for the phase ratio, and uncertainty as to whether the di...

摘要:Pesticides are often chiral, and their isomers have different activity, toxicity, metabolism, and degradation properties. Perhaps, the most complex are the synthetic pyrethroid insecticides that have up to 8 stereoisomers, but not all are active. Pyrethroids are toxic to aqu...

摘要:For the first time, a multi-lumen capillary (MLC) (126 parallel channels of 4.2 µm i.d) has been modified to produce a C18-functionalised silica porous layer open tubular (PLOT) capillary column for both on-capillary preconcentration and separation. The modified multi-lumen ...

摘要:The simultaneous liquid chromatographic analysis of water- and fat-soluble vitamins is challenging because of their wide polarity range. Typically, water-soluble vitamins are separated and analyzed by hydrophilic interaction chromatography (HILIC) while fat-soluble vitamins ...

摘要:Amino acids and peptides (di- and tripeptides) as chemically bonded ligands in liquid chromatography were investigated. The comparison between 9 home-made amino acid- and peptide-silica stationary phases in hydrophilic interaction liquid chromatography (HILIC) and reversed-p...

摘要:Phenolics are a large group of secondary plant metabolites that are of interest because of their proposed health benefits. The analysis of plant phenolics is challenging due to their extreme structural diversity. Comprehensive two-dimensional liquid chromatography (LC × LC) ...

摘要:Currently, state-of-the-art analytical methods for multiclass, multiresidue monitoring of pesticides in foods use ultrahigh performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) for analysis of LC-amenable analytes. UHPLC-MS/MS for > 100 pesticides typical...
