Merck Purospher® Columns

The Purospher® RP-18 column is polar endcapped and suitable for separations of strong basic or chelating compounds (no acidic compounds) and separations of hydrophilic compounds with a high percentage of water in the mobile phase.

The Purospher® RP-18 endcapped column is suitable for separations of compley samples with simple eluents.

The Purospher® RP-18 HC column is not endcapped and is suitable for separations of polar, non-basic compounds.

The Purospher® STAR RP-18 endcapped column allows the tailing-free separation of neutral, acidic, basic or chelating compounds and is available as a special UHPLC column.

THe Purospher® STAR RP-8 endcapped column is suitable for separations of polar compounds or separation of positionally isomeric compounds.
