Time-modified second batch experiment
As mentioned above, during the second batch experiment there were several
problems arisen with the pilot column system. Those problems are shown in every
breakthrough curve of the second batch experiment as a “temporary stabilization” of
the curve. In this section those “stabilizations” were counted as “dead times” and a
proper time modification was applied for every curve to restore its continuity.
