Overview

The Brownlee SPP (Superficially Porous Particle) RP-Amide column contains 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. This column is 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. It can be used to enhance the performance of both traditional HPLC systems and UHPLC systems and is compatible with 2 µm inlet frits, so traditional solvents and sample preparation techniques can be used. Specialized filters are not needed for UHPLC systems.

  • Coverage: 3.0 μmol/m²

  • pH Range: 2.0-9.0
  • Pressure Limit (UHPLC): 9,000 psi (620 bar)
  • Temperature Limit: 30°C
  • USP Code: L60
