TSKgel Octyl-80TS
TSKgel Octyl-80TS is based on a high-purity, metal free silica with 10 nm pore size bonded to C8 groups. It is completely endcapped and the resulting effective pore size is 8 nm (80 Å). TSKgel Octyl-80TS columns reduce tailing when analyzing basic compounds. They have a lower carbon load and hydrophobicity than the corresponding ODS products.
