PLOT COLUMNS
Fused Silica Silica BOND Columns
Rt®-Silica BOND Columns
(fused silica PLOT)
• Versatile column ideal for analysis of light hydrocarbons, sulfur gases, halocarbons,
and carbon dioxide.
• Individually QC tested with sensitive C4 probes to ensure consistent selectivity.
• Proprietary manufacturing process practically eliminates particle release, reducing
downtime due to obstructed FID jets.
• Bonded silica stationary phase minimizes impact of water, resulting in reproducible
retention times for water-containing samples.
• Stable to 260 °C.
Restek’s Rt®-Silica BOND columns are robust, versatile, selective PLOT columns that
offer excellent performance for the analysis of light hydrocarbons, sulfur gases, and
halocarbons above ambient temperature. In addition, carbon dioxide and other gases
can be retained at ambient temperature on this silica-based column. High loadability,
inertness, and consistent selectivity, as well as unmatched robustness at a maximum
temperature of 260 °C, make the Rt®-Silica BOND column ideal for the analysis of ac-
tive unsaturated hydrocarbons.
Rigorous C4 selectivity testing and additional testing to confirm efficiency and inert-
ness ensure good separations are achieved with optimal peak shape and response for
active analytes. As with all Restek® PLOT columns, our proprietary manufacturing
process minimizes particle generation, which reduces the problems commonly asso-
ciated with released particles (signal spikes, valve damage, and obstructed FID jets).
