100 angstrom and 120 angstrom ultra-pure silica with a high surface area modified with phenyl, phenyl-butyl or phenyl-hexyl. ZEOsphere phenyl phases as reversed phase or in hydrophilic interaction liquid chromatography (HILIC) mode show alternative selectivity to C18 and C8 columns. The phenyl group provides the stationary phase with a moderate degree of hydrophobicity, making it ideal for the separation of analyte mixtures with different polarity and aromaticity. Key applications include small water-soluble molecules and peptides, π-acceptors, nitroaromatics, polar compounds, dipoles, heterocycles and HILIC mode.
Also available: phenyl-hexyl and phenyl-butyl.
