Inertsil Diol HPLC Columns

Inertsil Diol

Inertsil Diol has a dihydroxypropyl group-bonded phase with unique selectivity in normal mode. The separation mechanism of the diol column is dominated by hydrogen bonding interactions between the diol groups and polar compounds. Diol columns provide an alternative selectivity to silica columns, often with increased retentivity.
