Brownlee SPP (Superficially Porous Particle) PhenylHexyl guard columns are base-deactivated for good peak shapes when separating basic compounds. They contain a hexyl spacer to provide optimal flexibility for the phenyl ring to facilitate π-π interactions with solutes. These columns are filled with 2.7 μm superficially porous particles that contain a 1.7 μm solid inner core and a 0.5 μm porous silica outer shell, allowing for a shorter diffusion path and nearly double the efficiency compared to traditional fully porous silica particles. These guard columns can be used to enhance the performance of both traditional HPLC systems and UHPLC systems.
