this phase can move along with the components. Consequently, the mobile phase runs through the stationary phase along with the sample. The sample dissolves in the mobile phase and migrates through the stationary phase. The mobile phase is either a liquid or a gas. ...
The reversed-phase high-performance liquid chromatographic separation of the ten major conjugated bile acids of man using isocratic conditions is described. Each component of the mobile and stationary phases was examined for its ability to influence the separation selectivity. Manipulation of pH, buffer...

The optimization of enantiomeric resolution by mobile phase variation was studied with the chiral stationary phase derived from R-N-(3,5-dinitrobenzoyl) phenylglycine covalently coupled to 5 脦录m spherical 3-aminopropyl silica. Chromatography was routinely performed with mobile phase compositions having...
The invention relates to elements for separating substances by distributing between a stationary and a mobile phase. Said separating elements comprise any stationary phase and a support element. The separating elements are part of a set that is provided with at least two separating elements T(i=2...
Particle sizes must be small—for example, 35–50 μm and 25–35 μm. There are various methods of packing the stationary phase into the column. Materials such as ion-exchange resins, which swell when they come into contact with a solvent, must be packed wet as a slurry. Other ...
Zwitterionic surfactants immobilized on the surfaces of octadecylsilica (ODS) are used for the stationary phase and water as the mobile phase for the ion chromatography (IC) of target analytes. The creation of an electrical double layer (EDL), when a zwitterionic stationary phase is in contact ...

partitioning mechanism, both the mobile and stationary phases play important roles in the separation; the solute of interest has cer- tain specific interactions with the stationary phase, which allow the separation to occur. Solutes spend the same amount of time in the mobile phase, which enabl...
