Brownlee SPP Columns

Brownlee SPP (Superficially Porous Particle) C18 columns are high purity and exhibit excellent peak shapes for a wide range of compounds using reverse phase separation. They 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. The columns can be used to enhance the performance of both traditional HPLC systems and UHPLC systems.
