High-Performance liquid Chromatography

2020
Gas chromatography has developed over the past 25 years or so into one of the most extensively used on-line analytical techniques in industrial process control and optimization. Liquid chromatography, and its several individual techniques, is firmly established in the laboratory, but its on-line process use has not developed as rapidly as GC.

High performance “ionic liquid” chromatography

Chemical Communications, 2011
We firstly developed high performance liquid chromatography methods with "ionic liquids" as eluents (HPILC) and successfully demonstrated the analysis of various biopolymers including scarcely soluble highly polymerized cellulose by means of HPILC with highly polar ionic liquid.

High-performance liquid magneto-chromatography

Journal of Chromatography A, 2006
High-performance liquid magneto-chromatography (HPLMC) is a new chromatography technique with two distinctive features: (a) a high surface area stationary phase with paramagnetic properties composed of magnetite embedded in a silica gel, and (b) a magnetic field (variable intensity 0-5.5 mT) that selectively retains paramagnetic substances in the ...

Column Characterization and Selection Systems in Reversed-Phase High-Performance Liquid Chromatography.

Chemical Reviews, 2019
Reversed-phase high-performance liquid chromatography (RP-HPLC) is the most popular chromatographic mode, accounting for more than 90% of all separations.

High-performance liquid-liquid chromatography

Journal of Chromatography A, 1984
Abstract 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.
