ISO 23484:2023 is an international standard that provides a method for determining particle concentration in suspensions using small-angle X-ray scattering (SAXS). It specifies the procedure for measuring the concentration of spherical particles that are sufficiently monodisperse (i.e., of similar size). The standard was published in 2023 and focuses on using SAXS, a technique that scatters X-rays from a suspension of particles, to determine their concentration.
