Promosil® C18 Series Columns

High Performance, Exceptional Value

The Promosil® C18 series columns from Bonna-Agela Technologies are manufactured using ultra-pure monosilane and a tightly controlled bonding process, resulting in high surface coverage and complete end-capping. With a carbon content up to 18%, these columns deliver strong hydrophobic retention and enhanced analyte interaction.

Designed for stability across a pH range of 1.5 to 9.0, Promosil® C18 columns provide excellent peak shape for both acidic and basic compounds. Their high resistance to contamination and long operational life make them a cost-effective solution for routine and demanding reversed-phase applications alike.

Key Features:

• High-purity monosilane bonding for superior column reproducibility

• 18% carbon loading ensures strong retention and broad analyte compatibility

• Stable from pH 1.5 to 9.0, ideal for a wide range of method conditions

• Excellent peak shape for both polar and non-polar analytes

• High resistance to fouling and extended column lifetime

• Outstanding performance-to-cost ratio
