Published data on the sizes of small molecules measured by gel permeation chromatography are reconsidered after subjecting them to a recalculation procedure which gives molecular sizes in consistent units. Almost half the results are rejected as being unreliable. A set of molar volume values for n‐alkanes is recommended as a standard which should be used to calibrate gel permeation chromatographs irrespective of operating conditions. Molar volumes of some simple gases are given.
