The use of polychromatic Bremsstrahlung X‐rays generated by commercial tubes for energy‐dispersive small‐angle scattering measurements has not been extensively discussed in the literature, mainly because of some difficulties associated with it. If a suitable experimental setup is chosen and concomitant phenomena are taken into account for correcting the observed X‐ray patterns, energy‐dispersive small‐angle X‐ray scattering (SAXS) may become an interesting alternative to conventional measurements based on monochromatic beams. Energy‐dispersive SAXS experiments carried out on protein solutions, micelles, semicrystalline polymers and catalytic systems are discussed to illustrate the new opportunities offered by this technique as well as its limitations.
