ACE1290303
ACE C18-AR uses a proprietary bonding and end-capping process to produce a very rugged and robust octadecyl-phenyl (C18-AR) single phase. ACE columns are manufactured using ultra-pure based-deactivated silica that has extremely low silanol activity. This ultra-pure silica is efficiently bonded and exhaustively end-capped using proprietary technology. The result is silica based stationary phase that has virtually eliminated the negative effects of silanols on chromatographic separations. The ACE C18-AR leverages the selectivity of a C18 and a phenyl phase to separate mixtures that are very difficult to separate with either single phase alone. The ultra-inert characteristics of the ACE C18-AR Columns make them the ideal choice for separating analytes that differ in hydrophobicity, electron-poor analytes with electron delocalization and electron withdrawing groups (i.e. halogens, nitro groups, ketones, esters, and acids). Recommended applications for basic analytes, heterocycles, proton donors and acceptors, and halogenated aromatics. ACE columns consistently produce measurably better peak shape and column efficiency when separating troublesome compounds. ACE C18-AR is also compatible with 100% Aqueous mobile phases for enhanced retention in reversed phase mode. ACE C18-AR is available in 3 micron and 5 micron particles sizes. ACE C18-AR has a surface area of 300 m2/g and a carbon load of 15.5%. ACE C18 has a recommended pH range of 2-8; working outside these ranges will reduce column lifetime. ACE C18-AR is also available for UHPLC applications under the brand name ACE EXCEL C18-AR 2 micron UHPLC columns.
