Small angle X-ray scattering (SAXS) provides information on particle size and shape, as well as particle packing. Moreover, this technique is suitable to study a range of samples from very dilute to highly concentrated. A number of pharmaceutical delivery technologies have strict particle size limitations. X-ray small angle scattering can be a powerful technique giving critical information on particle size down to small lengths scales. This presentation will describe the basics of SAXS as well as some applications applied to pharmaceutically relevant samples.
