High Pressure Liquid Chromatography

Journal of Pharmaceutical Sciences, 1973
Abstract Prior to 1967, liquid column chromatography (LCC) separations were not normally carried out in an optimum manner; for this reason, the technique was viewed as slow and inefficient (1–3). Consequently, other techniques such as thin-layer chromatography (TLC) and gas chromatography (GC) found favor.

Analysis of Trisulfapyrimidines by High-Pressure Liquid Chromatography

Journal of Pharmaceutical Sciences, 1973
Abstract: The application of high-pressure liquid chromatography to the separation and analysis of trisulfapyrimidines in pharmaceutical dosage forms is demonstrated. The preparation of samples of both tablet and suspension dosage forms is simple and rapid.

Effects of high pressure in liquid chromatography

Journal of Chromatography A, 2005
All the experimental parameters that the chromatographers are used to consider as constant (the column length and its diameter, the particle size, the column porosities, the phase ratio, the column hold-up volume, the pressure gradient along the column, the mobile phase density and its viscosity, the diffusion coefficients, the equilibrium constants ...

High pressure liquid chromatography of oligodeoxyribonucleotides

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1973
Abstract A high pressure liquid chromatography system capable of resolving oligodeoxy-ribonucleotides of intermediate size is described. Columns filled with a pellicular weak anion exchanger consisting of a polymeric aliphatic amine permit the rapid resolution of small amounts of oligomers.

Method transfer from high-pressure liquid chromatography to ultra-high-pressure liquid chromatography. II. Temperature and pressure effects

Journal of Chromatography A, 2015
The importance of the generated temperature and pressure gradients in ultra-high-pressure liquid chromatography (UHPLC) are investigated and compared to high-pressure liquid chromatography (HPLC).

High-pressure liquid chromatography of steroids

Journal of Chromatography A, 1979
After a brief discussion of the merits and limitations of high-pressure liquid chromatography (HPLC) relative to other chromatographic methods, special problems in the application to steroids are discussed. Publications on HPLC of steroids are then discussed under the headings of individual classes, arranged generally in the order of increasing ...

High-pressure liquid chromatography of peptides

Journal of Chromatography A, 1977
Peptides varying in size from di- to decapeptide have been subjected to high-pressure liquid chromatography on Phenyl-Corasil, Poragel PN, and Poragel PS under reversed-phase conditions with acetonitrile-water mixtures. It has been found that residual silanol groups in the Phenyl-Corasil and the functional groups in the Poragels significantly influence
