Sample cleanup is a very important step because methods often don’t respond to the analyte in its in-situ form, or the results can be distorted by interfering species. Column cleanup is used to eliminate interferences that can occur in the sample matrices. Multi-column cleanup procedures use multiple column chemistries to remove interferences and fractionate analytes of interest from complicated sample matrices.
