A new member of the HyPURITY® family introduced at Pittcon 2003, HyPURITY AQUASTAR™ columns are a new silica-based polar end-capped C18 which is designed to offer superior retention of polar compounds and increased sensitivity in 100% aqueous conditions. The robust nature of the bonded phase results in a silica-based column that is unsurpassed for LC and LC/MS applications. This next generation column also offers enhanced performance over first generation polar end-capped columns.
