Grace: Alltima HP

Alltima HP columns combine a range of different phase chemistries with high purity silica. The Alltima HP 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.

  

The general features of Alltima HP include:

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