PLOT Columns

Products

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.

MXT-Alumina BOND/MAPD Columns (Siltek-treated stainless steel 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.
  • Metal Siltek-treated tubing is incredibly durable, allowing MXT columns to be tightly coiled without breaking for use in smaller GC ovens.
