Different ways of treating the electromagnetic interaction in proton-proton scattering for energies between 20-750 MeV have been tested using phase-shift analysis. New formulae are presented in order to obtain a good separation of the nuclear and electromagnetic phase-shifts. Inclusion of the electromagnetic form factors improves the analysis above 300 MeV. The ppπ0 pseudovector coupling constant used in the phase-shift analysis was varied and the χ2 surface was studied in six energy intervals.
