Rt®-Alumina BOND/MAPD Columns

(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.

Restek’s R&D chemists have optimized the deactivation technology applied to our

Rt®-Alumina BOND/MAPD column for improved analysis of trace concentrations of

polar hydrocarbons like acetylene, methyl acetylene, and propadiene in hydrocarbon

streams containing higher levels of C1-C5 hydrocarbons. Our alumina PLOT deac-

tivation produces an incredibly inert column that offers superior reproducibility and

stable response factors to maximize the number of analyses before recalibration is re-

quired. Its high sample capacity reduces peak tailing, thereby improving the separation

of target compounds. In addition, a 250 °C maximum operating temperature lets you

more quickly elute hydrocarbons up to dodecane and reduces regeneration time when

the column is exposed to water from samples or carrier gases.
