标准范围

本文件提供了使用静态多重光散射(SMLS)技术测定分散在液体中的纳米物体(即颗粒、液滴或气泡)的平均(球形)等效直径的指南和要求。该技术适用于多种材料,不需要稀释浓缩样品。

This document 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 static multiple light scattering (SMLS) technique. The technique is applicable to a wide range of materials and does not require dilution of concentrated samples.
