Cosmosil 5C8-MS alkyl-chained columns use packing material which combine alkyl chains (except C18) such asC8 (octyl), C4 (buty) and TMS (trimethyl). As the length of alkyl chain becomes shorter, the hydrophobic interaction becomes weaker.
Owing to the ultra end-capping treatment with very low levels of free silanol as in the case of C18 columns, COSMOSIL alkyl-chained columns can be used widely for the general analysis of compounds including those for which C18 columns produce long retention times.
