KNAUER Eurospher II 100 Phenyl Prep HPLC Columns (USP L11)

Phenyl columns for Reversed Phase in HPLC and UHPLC  (USP L11)

Phenyl stationary phases (USP L11) in reversed phase mode with alternative selectivity for:

• Aromatic and moderately π-π interaction polar analytes
• Mixtures with varying polarity and aromaticity

The polarity is similar to C8 modification but with different selectivity for polar aromatics, polycyclic aromatic hydrocarbons, fatty acids etc. Phenyl phases with a classical slightly hydrophobic endcapping or without endcapping.

Properties

• Separation mechanism: π-π interactions
• Ultra pure, spherical high performance HPLC phase based on silica gel
• Phenyl modification (Phenylpropyl), 12 % carbon content

Key features

• Classical phenyl phase with 12 % carbon load, outstanding mechanical and chemical stability, suited for analytical as well as semi preparative and preparative applications.

Recommended application areas

• Alternative selectivity for aromatic and mode rately pi-pi interaction polar analytes or mixtures with varying polarity and aromaticity.

KNAUER: Phenyl

Tip: For UHPLC columns like Eurospher II 2 μm particle size, samples and eluents should be filtered through a 0.2 μm instead of a 0.45 μm membrane filter. Frits at column inand outlet have smaller pores than classical HPLC columns and block more easily.

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

Eurospher II 100 Phenyl Preparative Standard Columns are available with these parameters:

• Column length (mm): 50, 150, 250
