Track membranes are prepared by irradiation by energetic heavy ions. They are then etched by a suitable chemical solution, which creates uniform, nearly monodisperse channels. Small‐angle X‐ray scattering by the nanochannels gives typical patterns. New experimental protocol and data treatment allow one to obtain information about the channel diameter and dispersion, wall thickness and roughness.
