High-performance liquid-liquid chromatography
Journal of Chromatography A, 1984Abstract The applicability of liquid-liquid systems as phase systems in high-performance liquid chromatography (HPLC) was investigated. The more polar phase of the liquid-liquid system is generated in situ on pre-packed silica columns by pumping through the saturated mobile phase.

A new set of hydrophilicity high-performance liquid chromatography (HPLC) parameters is presented. These parameters were derived from the retention times of 20 model synthetic peptides, Ac-Gly-X-X-(Leu)3-(Lys)2-amide, where X was substituted with the 20 ...

High Performance Liquid Chromatography
2003High performance liquid chromatography (HPLC) has many applications in food chemistry. Food components that have been analyzed with HPLC include organic acids, vitamins, amino acids, sugars, nitrosamines, certain pesticides, metabolites, fatty acids, aflatoxins, pigments, and certain food additives.

Chromatography: High-Performance Liquid Chromatography
2016High-performance liquid chromatography (HPLC) is a major analytic tool in contemporary science, with possibly the highest number of systems installed and running globally. Modern HPLC offers high resolutions allowing the quantitative determination of target analytes within complex matrices by its compatibility with a number of detectors.

High-Performance Liquid Chromatography
2001Chromatography is a general term applied to a wide variety of separation techniques based on the sample partitioning between a moving phase, which can be a gas, liquid, or supercritical fluid, and a stationary phase, which may be either a liquid or a solid.

High-performance liquid chromatography of porphyrins
Journal of Chromatography B: Biomedical Sciences and Applications, 1988Techniques for the analysis of porphyrins in the biomedical fields are reviewed. The emphasis is on high-performance liquid chromatography and its aspplications in: (1) the quantitative analysis of porphyrins in blood, urine and faeces; (2) qualitative porphyrin profiles in normal subjects and in the porphyrias; (3) assay of haem biosynthetic enzyme ...
