The use of ethylene glycol as the stationary phase for the separation of corticosteroids and of 17-ketosteroids by paper chromatography is proposed. Some characteristics of systems with ethylene glycol in the stationary phase are described.doi:10.1016/S0021-9673(01)86296-8Luboš Stárka...
Further, as the effectiveness of the stationary phase can only be considered in relation to the column type, a chapter on different column types and the arrangement of the stationary phase within the column is included. 展开 关键词: Gas chromatography, Stationary phase (Chromatography ...
The retention and selectivity of solutes in reversed-phase liquid chromatography is related to the mobile phase and the stationary phase effects. The mobile phase effect, related to the hydrophobic cavity formation around non-polar solutes, is assumed to have a dominant effect on retention upon ...
In ion-pair reversed-phase chromatography, the retention of Ionized analytes on a nonpolar bonded stationary phase Is enhanced by the presence of a "hydrophobic" counterion (hetaeron) In the mobile phase. Either ion-pair formation in the... C Horvath,W Melander,I Molnar,... - 《Analytical...
Preparation of stationary phases for open-tubular capillary electrochromatography using the sol-gel method Capillary electrochromatography requires the deposition of a stationary phase inside the capillary. In this paper the sol鈥揼el method is proposed for this... S Constantin,R Freitag - 《Journal ...
Preparation and evaluation ofp-tert-butyl-calix[4]arene-bonded silica stationary phases for high performance liquid chromatography A new method is proposed for preparation of a p-tert -butyl-calix[4]arene-bonded silica stationary phase. The chemically modified p-tert -butyl-calix[4]are... XZ Xi...
Chiral stationary phases (CSPs) have the potential for the analytical and preparative resolution of chiral drugs by chromatographies.This paper highlights five categories of chromatographic techniques with CSPs,four mobile-phase regimens in HPLC-Supercritical Fluid Chromatography (SFC) CSPs and six categ...
molecularly imprinted polymers that are useful for the quantitative determination of polychlorinated biphenyls in environmental matrices, which provides a low-cost strategy for tailoring stationary phases that avoid template leaching in applications in solid-phase extraction as well as liquid chromatography. ...
Several different derivatized {beta}-cyclodextrins were synthesized and used as chiral stationary phases in normal-phase liquid chromatography. The multipl... DW Armstrong,AM Stalcup,ML Hilton,... - 《Analytical Chemistry》 被引量: 226发表: 1990年 ...
