Chromatograms

Both chromatograms below 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.
