Acclaim PolarAdvantage 3UM 3X250MM Novel polar-embedded reversed-phase columns with unique selectivity • Selectivity complementary to the C18 column • Low silanol activity for excellent peak shape with basic compounds • Compatible with 100% aqueous mobile phase • High selectivity for hydrophobic aromatic molecules • Wide range of applications Acclaim PolarAdvantage (PA) columns feature a patented bonding column chemistry that incorporates a polar sulfonamide group with an ether linkage near the silica surface. This unique chemistry provides low silanol activity, compatibility with 100% aqueous mobile phase. The Acclaim PA column offers great separation power to resolve a wide variety of polar and non-polar analytes and supports LC-MS analysis.
