WebApr 14, 2007 · C8 vs C18 columns. Here's a question. We all know that C8 columns give somewhat less retention than C18. And that C8 columns also show less tailing because the analytes have more 'equal access' to the active sites: vs the situation with C18 where only a fraction of the molecules can interact with the active sites.
