Avantor® Alltima HP columns combine a range of different phase chemistries with high purity silica. Avantor® Alltima HP columns contain the highest carbon load for superior retention and loadability.

• High purity silica
• Excellent column stability
• Low to no detectable column bleed
• Multiple selectivity options

These columns have greater retention and enhanced peak symmetry for polar compounds for reversed-phase applications where C18 is too retentive.

These product family combines the selectivity and performance needed to overcome the most challenging separation needs. The low column bleed makes these columns ideal for microbore applications.
