| AichromBond-AQ C18 |
¡ñ Inertness: it is one of most base-friendly columns, comparable with Xterra and even better than Inertsil, is far better than Kromasil and Hypersil.
¡ñ Efficiency: the best for polar compounds at any pH.
¡ñ Large volume injection: maintain very high efficiency even if the injection volume is exceptional large.
¡ñ 100% water compatible: very unique for a universal C18 column; far better peak shape, retention and efficiency than those so-called high aqueous ¡°AQ¡± columns.
¡ñ Low pH Stability (pH=1.5): next to the Zorbax SB C18, it has better stability than most of popular brand columns on the market, and is far better than any domestic column at low pH. |
