Overview

Brownlee SPP (Superficially Porous Particle) PFP (pentafluoro-phenylpropyl) guard columns are pentafluorophenyl with a propyl spacer. 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.
