“…This property gives rise to differences in the electroendosmotic flow characteristics as well as peptide selectivity. After the etching process, the modification of the surface with OT-CEC capillaries can be accomplished through a silanization step that creates a hydride layer as an intermediate followed by a hydrosilation reaction to attach the organic moiety [8][9][10]. The complete process for the fabrication of etched chemically modified capillaries can be represented by the schemata (Fig.…”

“…A cloração seguida de reação com reagente de Grignard ou composto organo-lítio também foi empregada 31 na modificação da sílica e consiste de uma etapa de cloração superficial com cloreto de tionila (reação 3), seguida pela ligação da cadeia alquila através de um reagente de Grignard (reação 4) ou um composto organo-lítio (reação 5).…”

“…Theoretically, chromato-graphic effects could be observed in etched but not chemically modified capillaries, etched physically coated capillaries, and etched chemically bonded capillaries. To date, the above studies [18±20] and others [21±23] have focused on the latter approach where the etched capillary was subsequently modified via a silanization/hydrosilation [24] reaction sequence. In all cases, ammonium hydrogen difluoride was used as the etching agent.…”
