by Hichrome
The Alltima HPLC column range was developed by Alltech. Hichrom acquired the entire range from Grace. Alltima phases are acid and base-deactivated, giving excellent peak shape for acids, bases, and neutrals in a single run. Polymerically bonded and double-endcapped for long column lifetimes, Alltima columns are great general purpose “workhorse” columns.
Base deactivated silica;
Stable bonding for long column lifetime;
Symmetrical peak shape;
Alltima C18 phase provide classic reversed-phase retention and selectivity. High quality hydrophobic general purpose C18.
