Aluspher® RP selectB by Merck KGaA, Darmstadt, Germany
A versatile alkaline stabile reversed phase stationary phase for use with basic eluents: Aluspher® RP-select B is ideal when using basic eluents as ionisation of basic compounds is depressed and peak-tailing is avoided. Aluspher® RP-select B is a alkali-stabile reversed phase stationary phase designed for the separation of neutral, basic and acidic compounds when using basic eluents. Due to its stability in the pH range of pH 2-12 Aluspher® RP-select B allows use of basic eluents like NaOH.
