KNAUER Eurospher II 100 C18P (U)HPLC Columns (USP L1)

C18P columns with trifunctional modifications (USP L1): Hydrophobic and stearic interactions

KNAUER´s most unpolar C18P phase with excellent shape selectivity. It features polymeric, high efficiency endcapping of 99 % and 20 % carbon content, exceptional pH stability in the range of 1–12, and outstanding mechanical and chemical stability.

Properties

• Separation mechanism: Hydrophobic and stearic interaction
• Ultra pure, spherical high performance HPLC phase based on silica gel
• Unpolar, trifunctional C18 (Octadecyl) modification, high efficiency endcapping, with 20 % carbon content (~ 99 % endcapping) 

Key features

• KNAUER´s most unpolar C18 phase, polymeric, high efficiency endcapping of 99 % and 20 % carbon content, higher pH stability in the range of 1-12, outstanding mechanical and chemical stability, suited for analytical as well as semi preparative and preparative applications.

Recommended application areas

• Alternative selectivity to standard C18; stationary phase in Eurospher II C18 family with the highest carbon load; fully endcapped; excellent shape selectivity and pH stability.

KNAUER: C18P

Tip: Not all C18 phases are comparable! When replacing an existing column, always have a close look at the characteristics like carbon load, pore size and specific surface area.
