NOVELTY - The method involves drying graphene sample in a vacuum drying chamber. The graphene sample is filled in an inner part of a fill column. The fill column is installed in a column chromatographic column. Temperature of a column box is about 180 degrees centigrade. Column pressure correcting factor of the column chromatographic column is obtained. A nalkane molecule absorbing free energy negative value is calculated. An avogadro constant value of a table area is calculated. USE - Reverse phase chromatography based pneuma graphene surface free energy dispersion determining method. ADVANTAGE - The method enables realizing reverse phase chromatography based pneuma graphene surface free energy dispersion determining process in a simple manner with high reliability.
