1. A method of identifying and/or characterising ions, the method comprising:
separating analyte ions according to a first physico-chemical property;
selecting first ions of the analyte ions, and activating, fragmenting or reacting the first ions to produce first product ions;
separating the first product ions according to the first physico-chemical property, and determining a pattern of the first product ions; and
identifying and/or characterising the first ions using the pattern of the first product ions.
