Sometimes, you may see a Partisil HPLC column referred to as "ODS." This means the column has an Octadecyl silane (C18) stationary phase. In addition, you may see ODS followed by a number designation:

     Partisil™ ODS is a low carbon load C18 phase, with intentionally unbonded surface silanols adding to the selectivity.

     Partisil ODS2 is a relatively high carbon load C18 bonded silica phase which makes it the most non-polar and, therefore, the most retentive of the Partisil reversed-phase columns. The high sample load capacity is suitable for preparative work.

     Partisil ODS3 is an intermediate carbon load C18 phase used for pharmaceutical, natural products, food, biological and environmental pollutants applications.
