These Sentry Guard Cartridges are designed to retain extremely polar compounds, such as carbohydrates and sugars. They feature a chemically stable, trifunctionally bonded amide phase, stable from pH 2 to 11, for separating polar analytes across a wide range of polarity and pKa.

  • Retains extremely polar compounds (e.g., carbohydrates, sugars).
  • Chemically stable, trifunctionally bonded amide phase.
  • Stable across a wide pH range (2 to 11).
  • Separates polar analytes with varied polarity and pKa.
  • Protects analytical columns by trapping particulates and strongly retained compounds.
  • Ideal for HILIC applications, including sugars, glycols, and polar compounds.
  • Compatible with common HILIC solvents (e.g., acetonitrile, water with buffers).
