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).
