Rtx®-2887Column
(fusedsilica)
(nonpolar phase; Crossbond®100%dimethyl polysiloxane—for simulateddistillation)
• Application-specific column for simulateddistillation.
• Stable to360 °C.
TheRtx®-2887 column’s stationaryphase, columndimensions, and film thicknesshave
been optimized to exceed the resolution and skewing factor requirements currently
specified inASTMmethodD2887. Each column is individually tested to guarantee a
stable baseline with low bleed and reproducible retention times. The Crossbond®
methyl silicone stationary phase has increased stability compared to packed columns,
ensuring stable baselines and shorter conditioning times.
