The Venusil AQ C18 column is designed for the separation of polar, medium-polar and non-polar compounds at low to medium pH. This column is more polar than XBP C18, but less polar than ASB C18. With a special surface treatment, Venusil AQ C18 is made to be compatible with 100% aqueous mobile phases, and it can be used to replace Waters Symmetry, Inertsil C18, Zorbax SB, Atlantis dC18, and other AQ columns.


This column has a pH range of 1.5-9.0. Pore size:100 Å; Specific surface: 380 m2/g; Purity>99.999%;

♦ Inertness: one of most base-friendly columns, excellent peak symmetry for basic compounds.

♦ Efficiency: The best column for polar compounds at any pH.

♦ Large volume injection: maintains very high efficiency even if the injection volume is exceptionally large.

♦ 100% water compatible: very unique for a universal C18 column; much better peak shape, retention, and efficiency than other brand AQ columns.

♦ Low pH stability (pH=1.5): better stability than most of the popular brand columns (including other brand AQ columns) on the market.
