TSKgel ODS-120A  columns use a 15nm pore size silica base support.  The silica's exclusion limit of 10,000 Da makes them a good choice for the reversed phase chromatography of peptides, small proteins, and environmental samples such as poly-aromatic hydrocarbons.

The "A" signifies that the material is not endcapped. For charged samples, the endcapped TSKgel ODS-120T column is a more suitable alternative.

Bonded phase pore size is indicated by the number in the product description, in this case TSKgel ODS-120A has 12nm nominal pore size.
