ISO 13320 Particle Size Distribution in Safety Testing of Nanoparticles

ISO 13320 Particle Size Distribution in Safety Testing of Nanoparticles

The ISO 13320 standard is a cornerstone in the field of nanotoxicology, providing a standardized method for measuring particle size distribution using laser diffraction. This service ensures that safety assessments are conducted accurately and consistently across industries.

Nanoparticles exhibit unique properties due to their small size and large surface area-to-volume ratio. These characteristics make them highly versatile in various applications such as medicine, electronics, and cosmetics. However, the same attributes can also pose potential risks to human health and the environment if not properly managed.

The ISO 13320 particle size distribution test is critical for ensuring that nanoparticles are used safely. By measuring the size distribution of these particles, we can assess their behavior in biological systems more accurately than with bulk materials. This information is essential for predicting potential adverse effects and developing appropriate safety measures.

The laser diffraction technique employed by this service captures a wide range of particle sizes from submicron to several millimeters. This broad coverage ensures comprehensive data that can be used across different research and development stages. The accuracy and precision of the results are further enhanced by automated calibration procedures and continuous quality control measures.

Our team of experts uses state-of-the-art equipment, including laser diffraction analyzers from leading manufacturers like Malvern Panalytical and Beckman Coulter. These instruments provide high-resolution data that can be used to identify specific particle size distributions and their corresponding volumes or masses.

The process begins with careful preparation of the sample, which involves dispersing the nanoparticles in a suitable medium such as water or ethanol. This dispersion step is crucial for obtaining accurate measurements since agglomerates may lead to erroneous results. After dispersion, the samples are analyzed using laser diffraction according to ISO 13320 guidelines.

The resulting particle size distribution curves provide valuable insights into how nanoparticles might behave under different conditions. For instance, smaller particles tend to penetrate biological barriers more easily than larger ones, which has significant implications for their toxicity and bioavailability. Additionally, the surface area-to-volume ratio increases with decreasing particle size, potentially enhancing reactivity.
