Small‐angle X‐ray scattering and size‐exclusion chromatography have been combined within a unified experimental set‐up to obtain molecular size information. Besides providing simultaneous corroborative data bearing on the same question from two distinct experimental techniques, passing the samples over a gel filtration column immediately prior to illumination by X‐rays provides both a more homogeneous sample and a continuous set of data as the concentration is extrapolated to zero. This greatly facilitates analysis of data from oligomerizing or aggregating proteins and increases the reliability of the results.
