ISO 13320 Nanoparticle Size Distribution by Laser Diffraction
The ISO 13320 standard provides a robust method for determining the size distribution of nanoparticles using laser diffraction. This technique is widely used across various sectors including pharmaceuticals, electronics, and environmental sciences due to its precision and efficiency.
By employing a laser beam that interacts with particles suspended in fluid, this method measures how the beam scatters at different angles. The intensity of scattered light correlates directly with particle size. This non-destructive approach allows for real-time analysis without altering the sample's properties. The result is a detailed size distribution histogram which can help in understanding the physical characteristics and behavior of nanoparticles.
The ISO 13320 method is particularly advantageous because it offers high accuracy over a wide range of particle sizes, from submicronic to several microns. This versatility makes it suitable for diverse applications where precise characterization of nanoparticle size distribution is essential. It’s also notable that this technique can be applied to a variety of sample types including liquids and suspensions.
The process involves several key steps: preparation of the sample, calibration of the instrument, measurement of the sample, and subsequent data analysis. Sample preparation typically includes dispersing nanoparticles in a suitable solvent or carrier fluid before introducing them into the laser beam path. Calibration ensures that the instrument accurately measures particle size. During measurement, particles are illuminated by the laser, and their scattered light is collected by a detector array. The resulting data is then processed to generate a histogram representing the distribution of particle sizes.
Instrumentation for ISO 13320 testing includes advanced laser diffraction instruments that provide reliable measurements. These devices come equipped with sophisticated software capable of interpreting raw data into meaningful size distributions. Reporting involves presenting this information in graphical form, often alongside statistical descriptors such as mean diameter and standard deviation.
- Preparation: Ensuring the sample is properly dispersed to avoid agglomeration or settling
