Combination of novel end-capping reagent with an ethylene chain and sunniest end-capping leads a silica C18 column to be stable under pH12 condition. Although Sunniest end-capping leaded to stability under pH10 condition.
SunArmor C18 can be used at pH range of a mobile phase between 2 to 12. This is almost same durability to compare with a hybrid C18s column. Furthermore SunArmor C18 shows better shape for acidic, basic and metal chelating compounds than the other hybrid C18 because of little residual silanol groups.
