Synthesis and Characteristics of New High Temperature Stationary Phase [60] Fullerene Polysiloxane for Capillary Gas Chromatography

Two new fullerene-containing polysiloxanes were synthesized by reacting [60] fullerene with azidepropyl polysiloxane directly and used as the stationary phases for capillary gas chromatography. It demonstrated a high column efficiency, wide operational temperature and outstanding thermostability. It can be used at 360°C with a baseline drift of 3 × 10-14 - 4 × 10-14 nm. The stationary phases were especially suitable for separation of high boiling compounds like monosaccharides, polycyclic aromatic hydrocarbons and phthalic diesters, etc. It was also found that some alcohols or aromatic positional isomers can be well separated on the column.
