These rugged reversed phase HPLC columns offer extended lifetime under extreme pH conditions and excellent stability for reproducible, high efficiency separations.

• Take full advantage of high and low pH conditions (pH 1 to 12) to manipulate selectivity
• Expect longer column lifetime with patented TWIN-NX™ technology
• Recommended for high efficiency analytical or preparative separations under extreme pH conditions
• Control selectivity of ionisable compounds for optimised methods
• High and low pH methods
• Consistent performance in both volatile and non-volatile buffers

TWIN-NX™ technology uses an improved patented organo-silica grafting process which incorporates highly stabilising ethane crosslinking.
