(29)Si NMR model dissolution study of the degradation of reversed phases for high-performance liquid chromatography

In order to simulate aging under chromatographic conditions, mono-, di- and trifunctional octyl and octadecyl derivatized reversed-phase high-performance liquid chromatography silicas were exposed to the very aggressive mobile phase-like medium. Monofunctional octyl phases were shown to deteriorate...

Zusammenfassung:In order to simulate aging under chromatographic conditions, mono-, di- and trifunctional octyl and octadecyl derivatized reversed-phase high-performance liquid chromatography silicas were exposed to the very aggressive mobile phase-like medium. Monofunctional octyl phases were shown to deteriorate through initial dissolution of monomeric ligand silane particles.
