(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.
