Further Evolution of surface modification
A combination of the novel end-capping reagent with an ethylene chain and sunniest end-capping leads a silica C18 column to be stable under pH12 conditions, although Sunniest end-capping leads to stability under pH10 condition.

SunArmor can be used at the pH range of a mobile phase between 2 to 12. This is almost the same durability compared to a hybrid C18s column.

Furthermore, SunArmor C18 shows better shape for acidic, basic, and metal chelating compounds than the other hybrid C18 because of small residual silanol groups.
