High Pressure Liquid Chromatography
Journal of Pharmaceutical Sciences, 1973Abstract 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.

High pressure liquid chromatography of oligodeoxyribonucleotides
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1973Abstract 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.

High-pressure liquid chromatography of steroids
Journal of Chromatography A, 1979After 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, 1977Peptides 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

High-back-pressure liquid chromatography
Journal of Chromatography A, 1982Abstract The retention behaviour of solutes on various stationary phases was studied by micro-high-performance liquid chromatography using liquefied solvents as the mobile phase. An octadecylsilylated stationary phase discriminates between coplanar and non-planar aromatic hydrocarbons in the normal-phase system using isobutane as the mobile phase ...
