Alltima™ HPLC columns are high quality, general purpose phases from the british specialist Hichrom. The base material is a spherical, base-deactivated silica gel, which is available with various modifications.
Alltima ™ HP Series HPLC Columns offer increased stability and performance compared to Alltima™ columns. They combine a range of different phase chemistries with high purity silica. The low column bleed makes these columns ideal for microbore applications.
