A method of separating compounds, includes: a. tagging at least a first organic compound with a first tagging moiety to result in a first tagged compound; b. tagging at least a second organic compound with a second tagging moiety different from the first tagging moiety to result in a second tagged compound, the first tagging moiety and the second tagging moiety including at least one of a common repeat unit, but having a different number of the repeat units therein, the greater the number of repeat units, the greater the polarity of the tagging moiety; and c. separating the first tagged compound from a mixture including at least the second tagged compound using a chromatographic separation technique based upon differences in the number of repeat units between the first tagging moiety and the second tagging moiety.
