ISO Publishes Standard for Determining the Mean Size of Nano-Objects in Liquid Dispersions by SMLS
The International Organization for Standardization (ISO) recently published ISO/TS 21357:2022, "Nanotechnologies -- Evaluation of the mean size of nano-objects in liquid dispersions by static multiple light scattering (SMLS)." See https://www.iso.org/standard/70759.html ISO states that the standard provides guidance and requirements for the determination of the mean (spherical) equivalent diameter of nano-objects (i.e., particles, droplets, or bubbles) dispersed in liquids using the SMLS technique. According to ISO, the technique is applicable to a wide range of materials and does not require dilution of concentrated samples.
