Solid, reliable Restek Roc C8 HPLC columns are pressure rated for any 400-bar HPLC system and deliver the peak shape, reproducibility, ruggedness, and performance you demand for all of your conventional HPLC applications. The general-purpose Restek Roc C8 is a conventional monomeric octylsilane column offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase. Like our Restek Roc C18, this general-purpose Restek Roc C8 is suitable for a wide range of compounds from acidic through slightly basic.
