ISO 18827 Nanoparticle Size Distribution in Colloidal Dispersions
The ISO 18827 standard provides a method for determining the size distribution of nanoparticles within colloidal dispersions. This is critical for ensuring product quality and compliance with regulatory requirements, especially in sectors like pharmaceuticals, cosmetics, and environmental sciences where nanoparticle behavior can significantly impact performance and safety.
The testing procedure involves the use of laser diffraction technology to measure particle size distribution over a wide range of diameters. The standard specifies detailed protocols for sample preparation, instrument calibration, and data analysis to ensure accurate and repeatable results. This method is particularly important when dealing with colloidal systems where particles may exhibit unusual behavior due to their small size.
Sample preparation is crucial in this process. Colloidal dispersions must be carefully prepared according to the ISO 18827 guidelines, which include homogenization and filtration steps to ensure a representative sample for analysis. The standard also emphasizes the importance of selecting appropriate dilution factors and dispersants to maintain particle stability during measurement.
The laser diffraction technique used in this procedure allows for rapid and precise measurement of particle size distribution. It operates by shining a laser through a colloidal dispersion, where scattered light is collected and analyzed to determine the size of particles present. This method provides high resolution and accuracy, even for very small nanoparticles.
Once measured, data analysis plays a critical role in interpreting the results. The ISO 18827 standard outlines specific procedures for processing raw scattering data into meaningful particle size distributions. This involves applying appropriate algorithms to account for factors such as refractive index and polydispersity of the sample.
