Uncoated Silica gel is the dominant stationary phase used in thin-layer chromatography (TLC). This constitutes an important difference to HPLC where most separations are carried out on chemically bonded phases by partition chromatography in the reversed-phase mode. Normal-phase separations by HPLC on...

The values of RMW and 0 lipophilic parameters obtained on RP18W, RP2, and CNF254 plates with the use of the a/m mobile phases, indicate that the investigated bile acids may be listed in order of decreasing lipophilicity as follows: LC>DC≈CDC≈GLC>C≈GDC>GC.doi:10.1080/10826070500224716...
By employing a mobile phase consisting of acetonitrile/methanol/water/acetic acid (96:2:2:0.1, v/v/v/v), nearly complete baseline separation (with α=1.08) of allantoin enantiomers was achieved in less than 15 min with both CSPs. Due to the “pseudo-enantiomeric” nature of the two ...

in mobile phase composition strongly influences the solvation shell of the polarized and polarizable units of the selectors and analytes, as well as ionizable mobile phase additives. Furthermore, the structural features of the selectors (e.g. the size of aromatic units and their substitution ...
The principle of chromatography is that molecules in the mixture are applied to a surface (the stationary phase) which is used to separate the mixture components while moving through the stationary phase with help of the mobile phase. There...
Stationary phase cells and media were collected after ten days incubation and analyzed by TLC and GLC. The con- centration of phytosterols and diosgenin was significantly greater in stationary phase cells incubated in media depleted of carbohydrates....
