Rtx®-2887 Column
(fused silica)
(nonpolar phase; Crossbond® 100% dimethyl polysiloxane—for simulated distillation)
• Application-specific column for simulated distillation.
• Stable to 360 °C.
The Rtx®-2887 column’s stationary phase, column dimensions, and film thickness have
been optimized to exceed the resolution and skewing factor requirements currently
specified in ASTM method D2887. 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.

MXT®-1HT SimDist Column
(Siltek® treated stainless steel)
(nonpolar phases)
• Stable up to 400 °C—lowest bleed for longest column lifetime.
• Reliably meets all ASTM D2887 specifications.
• 100% dimethyl polysiloxane phase allows easy comparisons to historical data.
