     2. the record of the results of a process of
        chromatography[2], produced by an instrument which
        measures some property related to the concentration of
        substances over the course of a chromatographic process.
        The record may be printed, for example, on a piece of
        paper, showing the concentration of some substance as a
        function of time or volume; or it may be retained in a
        computer and displayed on a video display terminal.
  
     Note: The analytical methods for determining which substances
           have moved to which point on the chromatogram are very
           varied, and the records of the results of a
           visualization techique, such as autoradiography, may
           itself be referred to as a chromatogram.
