Overview

Brownlee SPP (Superficially Porous Particle) C18 guard columns are high purity guard columns that exhibit excellent peak shapes for a wide range of compounds using reverse phase separation. 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.
