LC Chromatography Columns

General Purpose Octyl phase for reversed phase separations when less retention than a C18 is desired. High purity reversed phase packing that exhibits excellent peak shape for a wide range of compounds.

Brownlee SPP 2.7 µm C8 4.6 X 50 mm

Brownlee SPP 2.7 µm C8 4.6 X 75 mm

Brownlee SPP 2.7 µm HILIC 2.1 x 150 mm

Features and Benefits Solid inner core, porous silica outer shell, shorter diffusion path Very high efficiencies at moderate back pressures   Nearly twice the efficiency of 3-µm particle columns As robust as columns packed with 5-µm particles because
