TSKgel CN-80Ts is an alternative to C18 (ODS) and C8 (Octyl) phases. The cyano group is the least hydrophobic of the 100 Å phases available and in some cases is used under normal phase conditions. The chromatograms below show retention and selectivity of TSKgel CN-80Ts for 3 aromatic hydrocarbon compounds.

Bonded phase pore size is indicated by the number in the product description, in this case TSKgel CN-80Ts has 80 Å nominal pore size. The pore size of the base silica is 100 Å. 

CN-80Ts is useful for the analysis of polar peptides, amino acids, and other pharmaceutical and food & beverage products. As with other 80Ts products, TSKgel CN-80Ts provides reproducible separations of molecules below 6,000 MW.
