KNAUER Eurospher II 100 C18H (U)HPLC Columns (USP L1)

Hydrophobic / pH stable C18H Columns for more unpolar analytes in Reversed Phase (USP L1)

C18H stationary phase with a special, high efficiency or polymeric unpolar endcapping style. Because of the high carbon content and the protection of the Silica gel these materials are also suited for the use of mobile phase in an extended pH range from typically pH 1–12.

While a high endcapped C18H phase is characterized mostly by the high carbon content. A polymeric endcapped phase also provides an increased steric selectivity.

Properties

• Separation mechanism: Hydrophobic interaction
• Ultra pure, spherical high performance HPLC phase based on silica gel
• Nonpolar, monomeric C18 (Octadecyl) modification, high efficiency endcapping with 17 % carbon content (~ 99 % endcapping)

Key features

• Nonpolar C18 phase with high efficiency endcapping and 17 % carbon content, resulting in 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

• Recommended alternative to Kromasil 100 C18, for acidic, basic and neutral analytes in reversed phase mode with extended pH range.
