Retention behaviour of β-carbolines in normal-phase chromatography

, 1989
The retention behaviour of a series of β-carbolines in normal-phase chromatography was studied. Silica and amino phases in high-performance liquid (HPLC) and thin-layer chromatographic (TLC) systems were analyzed. The Snyder-Soczewinski approach was used

Quantitative structure‐retention relationships in reversed‐phase liquid chromatography using several stationary and mobile phases

, 2003
Quant. structure-retention relations (QSRRs) were employed to study retention mechanism of reversed-phase liq. chromatog. (RPLC). Two C18 and 2 C8 columns were used with mobile phases contg. MeOH, MeCN, and THF in concns. ranging from 40 to 90 (vol./vol.)

Refinement of Retention Indices in Gas Chromatography for a Number of Substituted Phenols

Analytica
Substituted phenols, including chlorophenols, are important analytes, particularly in the context of environmental analysis. Chlorophenols are formed during the disinfection of drinking water by chlorination and are important water pollutants.
