“…Safrole (3",4"-methylendioxyphenyl)propyl)-silica offers alternative selectivities compared to alkyl silica for most of the nitroaromatic compounds under investigation [5,38]. This characteristic is illustrated in Figure 1 where the retention factors k of some nitroaromatic substances are plotted for a C-18 column as well as for the safrole column.…”

“…The second column was a Merck cartridge (125 • 4 ram), packed in-house with safrole-silica which had been prepared from Kromasil-100 (5 pm) (Eka Nobel, Surte, Sweden) according to [5,38]. For the analyses of the field water sample, a Nucleosil C-18 guard column was used additionally.…”

A method for preparing a new polar substituted triazine stationary phase is described. The structure of the triazine phase on silica was characterized by elemental analysis, and by FfIR, solid state Ff_l3C NMR, and 29Si NMR spectral analysis. The chromatographic properties of this packing material have been evaluated by using a number of different solutes, and the properties compared with those of a commercial stationary phase RP-.l8.II is found that this triazine phase has weak z-doaor ligands on the silica surface.

A method for "Sock-Ball" chromatographic separation of high molecular weight fullerencs is described.A prepared sock-shaped stationary phase (Sock-SAF-phase) was used for HPLC separation of several polycyclic aromatic hydrocarbons (PARs) and fullerencs. Fullerenes, as ball-shaped molecules, are much more strongly retained than PARs on this stationary phase and have the eluted order C 60 < C 70 < C76 < C78 < C~4 in (he mobile phase of n-hexanefdichloromethane (100/0 -80/20). In contrast, chromatography on the Corresponding unmodified silica phase or 8C-30H-phase (an intermediate phase of Sock-SAF-phase) gave no separation of luHerenes. This fact indicated that the separation of fullerenes on Sock-SAF-phase was related to the selective interaction with the sock moiety.
