Brownlee SPP RP-Amide Guard Column - 5 mm x 3.0 mm I.D., Pkg. 3

Brownlee SPP (Superficially Porous Particle) RP-Amide guard columns contain a base-deactivated phase with a polar group within the alkyl bonded phase. This provides unique selectivity and a high level of base deactivation while reducing or eliminating the need for mobile phase additives. 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.
