GCColumns
• Unique selectivity forbaseline resolutionof all volatileamines.
• Excellent inertnessassuresaccuracyand sensitivity for volatileamines,
including freeammonia.
• Highly robustphasewithstands repeatedwater injections, resulting in
longer column lifetime.
• High temperature stability (290 °C) ensureselutionof aminesup toC16
andallows contaminants tobe removedby “bakingout” thecolumn.
