HPLC columns made in Japan

Inertsil ODS-HL Columns
Ultra High Retentivity
Ideal for Separation of Basic Molecules & its Related Substances, Process Impurities

High-Density Bonding of C18 Phase Delivers
Alternative Selectivity to Conventional C18 Columns

A mixture of o-, m- and p-terphenyl were separated under Acetonitrile and Water to compare the performance of planar molecule recognition between Inertsil ODS-HL and conventional C18 column. These three analytes differ only in their three-dimensional structure and not in their hydrophobicity or polarity. As shown below, Inertsil ODS-HL recognizes even slight steric differences achieving complete baseline separation while other conventional C18 column fails.
