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.

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.

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 ...
