The AGS consists of a Guard holder and guard cartridge, which is offered with various silica materials according to the stationary phase in the HPLC column used.

  • Universal – fits to virtually any column
  • The lowest influence on retention times compared with other guard systems
  • Small size for easier installation in the column oven
  • Any orientation of the cartridge
  • Pressure rating up to 900 bars
  • Higher bed capacity

Both chromatograms above show the separation of Uracil, Acetophenone, Toluene and Naphthalene with ARION® Guard system in Acetonitrile/Water (65:35) at 254 nm. ARION® Guard system does not affect column performance. It does not show any influence on peak symmetry or column resolution. A higher sorbent bed (5 × 4 mm ID) offers a raised capacity without need to couple two cartridges together. All this ensures lower running costs.
