The Unison UK-Phenyl column separates surfactants of different lengths better than a standard C18 column.

The Unison UK-Phenyl column effectively separates fluoroamphetamine and fluoromethamphetamine isomers with identical mass.

The Unison UK-Phenyl column is effectively able to separate triazolam and etizolam, which are very similar in structure.

Under neutral pH conditions, columns in the Unison and Cadenza series have similar retention and resolution properties.

Under acidic pH conditions, columns in the Unison and Cadenza series have similar retention and resolution properties.
