Description
Rt-Alumina BOND/MAPD Columns Material: (fused silica PLOT) • Optimized deactivation produces maximum response when analyzing trace levels of acetylene, methyl acetylene, and propadiene. • Stable response factors make this column ideal for process-type applications where recalibration must be minimized. • High loadability reduces peak tailing and improves separations. • Extended temperature range up to 250 °C for fast elution of high molecular weight (HMW) hydrocarbons and accelerated column regeneration following exposure to water. • Stable to 250 °C. Rt-Alumina BOND Columns Restek Rt-Alumina BOND columns are highly selective for C1–C5 hydrocarbons and separate all saturated and unsaturated hydrocarbon isomers above ambient temperatures. The reactivity of the aluminum oxide stationary phase is minimized, by deactivation with inorganic salts like KCl or Na2 SO4 , to improve column response for polar unsaturates, such as dienes, and the column's sensitivity (or response) ensures linear and quantitative chromatographic analysis for these compounds. Strong bonding minimizes particle generation and release, which allows valve switching with minimal risk to the injection or detection systems. And because they are stable up to at least 200 °C, Rt-Alumina BOND columns can be regenerated to restore full efficiency and selectivity by conditioning at their maximum temperature if water is adsorbed. High capacity and loadability give you exceptionally symmetrical peaks, making these columns ideal for volatile hydrocarbon separations at percent levels, as well as impurity analyses at ppm concentrations. Restek Rt-Alumina BOND PLOT columns are manufactured on fused silica tubing;
select phases are also available on metal MXT tubing. Similar Phases: Select Al2 O3 MAPD DF: 5 µm ID: 0.32 mm Length: 50 m Product Name: Rt-Alumina BOND/MAPD Product Type: GC Column Temp Limits: to 250 °C Units: ea.
