ISO 13320 Particle Size Distribution of Nanoparticles in Cleaning Liquids
The ISO 13320 standard provides a method for the measurement and determination of particle size distribution of nanoparticles in liquid samples. This is particularly important for cleaning liquids where the presence and distribution of nanoparticles can significantly impact product performance, efficacy, and safety.
Nanoparticles are often used in cleaning products due to their unique properties such as high reactivity, large surface area-to-volume ratio, and enhanced solubility. These characteristics make them effective at breaking down dirt, grime, and other contaminants but also raise concerns about potential health risks if not properly managed.
The ISO 13320 procedure involves the use of laser diffraction technology to measure the particle size distribution across a range of diameters from submicron up to several micrometers. This method is non-destructive and provides high precision, making it suitable for monitoring changes in nanoparticle concentration over time or between batches.
Preparation of samples before analysis involves dilution with appropriate solvents to ensure that nanoparticles remain suspended throughout the measurement process. It’s crucial to follow strict procedures to avoid agglomeration which can lead to erroneous size measurements.
The testing procedure itself requires careful calibration and standardization of equipment, adherence to recommended sample handling protocols, and interpretation of results considering potential interferences from dissolved substances or other particulates present in the cleaning liquid.
Results are typically reported as cumulative weight percent distribution curves showing the proportion of particles falling within various size intervals. These distributions help manufacturers understand how their products behave under different conditions and inform process optimization efforts aimed at achieving desired outcomes while minimizing adverse effects.
An important aspect of this testing is ensuring compliance with relevant regulations governing the use of nanomaterials in consumer goods. By accurately characterizing nanoparticle content, companies can demonstrate adherence to standards like ISO 13320 which provide a robust framework for consistent measurement practices across industries.
Understanding and adhering to such methods ensures that products not only meet performance expectations but also comply with safety guidelines protecting both users and the environment from potential risks associated with nanoparticle exposure.
