Phenomenological Theory of the PDC-Resolution

Since it has been clearly demonstrated that the above experimental fact cannot be explained by sorption of the transported polymer on some eventually uncovered glass beads or some metallic parts of the column1, the PDC-effect must obviously originate 

1 All elution curves were reproducible at 0.2% (or better), practically independently on the sample concentration from 0.5 to 5 mg/ml. A concentration-dependent knick occurred in these curves after replacing a 1 cm3 of the covered glass beads by uncovered ones. It is well known that sorption effects are concentration-dependent

After having stated the phenomenological theory of the PDC-resolution, yielding among others Eq. (19) of the PDC-calibration curves, a new field of investigation can be opened in PDC, namely that of the spreading phenomena.
