Kromasil Eternity-5-C18 30 mm

The Kromasil Eternity C18 Guard cartridges 30mm, 5µm, are used for column protection of Kromasil Eternity C18 HPLC columns with an internal diameter of 30mm are used. The cartridges contain a packing material matching the main column and protect the stationary phase from particles, matrix components and strongly eluting contaminants. The suitable direct holder 00000RHO is used as the guard cartridge holder.

Features and Benefits

• Eternity platform with a silica/organosilane surface for enhanced chemical stability
• Designed for reverse-phase separations under demanding pH and temperature conditions
• Particle sizes up to 2.5 µm for efficient HPLC methods
• Good column and batch reproducibility for method development and routine use
• Suitable for analytical applications, method transfer, and scale-up to preparative HPLC

Additional Information

Kromasil Eternity is based on the Kromasil 100 Å silica matrix and a silica/organosilane surface designed for greater chemical stability. This silica framework combines the mechanical stability and defined pore structure of the Kromasil platform with a surface that supports long stationary-phase lifetime even under more demanding pH conditions. The platform is designed for reverse-phase separations and facilitates method development, method transfer, and the scaling up of analytical columns to larger HPLC formats. Compatible Kromasil Eternity pre-column cartridges protect the packing bed of the analytical column and ensure reproducible retention times during routine operation.
