LiChroCART® Aluspher® HPLC Cartridges, EMD Millipore
Well suited for reversed phase chromatography of basic compounds. EMD LichroCart Aluspher
Cartridges are packed with spherical alumina sorbent particles, or spherical alumina sorbent
particles coated with polybutadiene (PBD). This PBD coated Aluspher® is named RP-Select B
because it mimics the reversed bonded silica phases. RP-Select B is an alkali-stable 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 2–12, RP-Select B can be used with basic
eluents like NaOH.
