Phenyl-Hexyl (USP L11)

Phenyl-Hexyl (USP L11) – Enhanced Hydrophobic and Aromatic Selectivity

Overview

Phenyl-Hexyl columns combine π-π interactions with enhanced hydrophobicity, providing an ideal balance for separating aromatic and non-aromatic compounds simultaneously.

Key Properties

Separation Mechanism: Combination of π-π and hydrophobic interactions.
pH Range: pH 2–9, optimized for mixed polarity compounds.
Carbon Load (100Å Pore Size): High-density bonding for better resolution.
Endcapping: Fully endcapped to reduce unwanted secondary interactions.

Performance & Benefits

✔ Increased Retention for Aromatic Analytes – Strong π-π selectivity.

✔ Versatile Selectivity – Suitable for both hydrophobic and aromatic compounds.

✔ Reproducibility & Efficiency – Ensures batch-to-batch consistency.

✔ Ideal for Complex Matrices – Excels in pharmaceutical and food testing.

Recommended Application Areas

Pharmaceuticals – Drug impurity profiling and metabolites.
Food & Beverage – Flavors, polyphenols, and preservatives.
Environmental Analysis – PAH detection in contaminated water.
