General description
Aluspher RP-select B is an alumina based alkali stable reversed phase stationary phase, designed for separations of neutral, acidic and basic compounds. Due to its stability in the range of pH 2-12 Aluspher RP-select B allows the use of basic eluents such as NaOH. This sorbent is packed into a LiChroCART 125-4 HPLC cartridge. The connection to the HPLC system is being accomplished by use of the manu-CART NT cartrige holder (1.51486).
