The SunArmor HPLC column provides a wide pH range from 2-12 for C18 and NH2 columns. The SunArmor RP-Aqua has a pH range of 2-10.
The Chromanik final end-capping technology with a newly developed silylating agent and TMS allows these columns to not be affected by residual silanol groups and shows a better peak shape of acidic, basic, and metal chelating compounds compared to competitors with hybrid C18 columns.
