Rt®-Alumina BOND/KCl Columns (fused silica PLOT)
(KCl deactivation)
• Restek’s lowest polarity alumina column.
• Low moisture sensitivity reduces the need for frequent regeneration.
• Acetylene elutes before n-butane.
• Methyl acetylene (impurity in 1,3-butadiene) elutes before 1,3-butadiene.
• Stable to 200 °C.
