Highly reproducible fabrication of porous layer open tubular (PLOT) structures in fused silica capillaries is often challenging; thus, methods to measure layer thickness growth in real time represent a powerful tool for the production of such columns...
High performance liquid chromatography-ultraviolet (HPLC-UV) was applied to the analysis and characterization of olive oils and other vegetable oils. A chromatographic separation on a Zorbax Eclipse XDB-C8 reversed-phase column was proposed under gra...
Countercurrent distribution based on liquid–liquid partition is a powerful separation method with minimal incurrence of loss of solutes, but its industrial application has been limited by cumbersome shifting of immiscible solvents. Although centrifug...
High-speed countercurrent chromatography with a spiral tube assembly can retain a satisfactory amount of stationary phase of polymer phase systems used for protein separation. In order to improve the partition efficiency, a simple tool was fabricated...
Occurrence of d-amino acids in living organisms is a useful indicator of various changes, diseases, or disorders. Determination of amino acid enantiomers, namely the enantiomeric ratio of amino acids or excess of certain d-amino acids, represents a u...
This review (4 tables, 88 references) describes current developments in the design and application of liquid chromatography electrochemical detection (LC ED) based approaches for the determination of drugs of abuse. Specific emphasis is placed on ope...
(1) Background: Countercurrent chromatography (CCC) is liquid-liquid partition chromatography without using a solid support matrix. This technique requires further improvement of peak resolution and shortening of separation time. (2) Methods: The lon...
