KNAUER Eurospher II 100 C18 (U)HPLC Columns (USP L1)

Classical Reversed Phase columns for HPLC and UHPLC (USP L1)

Most often used stationary phase in reversed phase mode. Silica gel based columns with C18 modification are available with or without endcapping. Classically endcapped phases are slightly more hydrophobic and unpolar than the not endcapped phases.

Properties

• Separation mechanism: Hydrophobic interaction
• Ultra pure, spherical high performance HPLC phase based on silica gel
• Unpolar, monomeric C18 (Octadecyl) modification, endcapped, with 16 % carbon content (~ 50 % endcapping).

Key features

• High-class HPLC phase perfectly suited to take on routine analyses as well as the most ambitious chromatography tasks, classical C18 phase with ca. 50 % endcapping and resulting 16 % carbon content, outstanding mechanical and chemical stability.

Recommended application areas

• acidic, basic and neutral analytes in reversed phase mode, for example sulphonamides
• anabolic steroids
• anti-psychotics
• beta blocker
• sudan dyes
• phenols and preservatives

KNAUER: C18 Non-endcapped

Tip: Caution! Never use classical C18 phases with 100 % aqueous mobile phase. The hydrophobic C18 chains will collapse

Stationary phase Eurospher II 100 C18 is provided in these column types: analytical, semi-preparative and preparative.
