Calibration Curves for KF-806L (Various Eluents: PS)

Calibration curves are shown for the GPC KF-806L with the following three different eluents. The difference of the calibration curves can be explained by the difference of molecular sizes of polystyrene. The three dimensional size of polystyrene is considered to be different depending on the kind of solvent in which the polystyrene is dissolved.
