Introduction:
As market demand for ultrafine nanopowders continues to grow, industries are looking for reliable ways to measure the particle size distribution of these materials. In this article, we will explore some of the most popular methods for measuring the particle size distribution of ultrafine nanopowders and highlight how SAT NANO is leading the way in providing high-quality ultrafine nanopowders.
Method 1: Dynamic Light Scattering (DLS)
Dynamic Light Scattering (DLS) is a popular method for measuring the size distribution of ultrafine nanopowders. DLS measures the fluctuations in the intensity of scattered light caused by particle Brownian motion. DLS is best suited to measuring small nanoparticles, with a size range typically between 0.1 nm to 10 µm. Commonly used in both industry and academia, DLS is a versatile and affordable method for measuring the particle size distribution of ultrafine nanopowders.
Method 2: Laser Diffraction
Laser diffraction is another common technique used to measure the particle size distribution of ultrafine nanopowders. This method measures the diffraction pattern of a laser beam as it passes through a sample. Laser diffraction is highly accurate and can measure particle sizes between 0.1 µm to 3,000 µm. However, it is not as sensitive to very small particles as DLS.
Method 3: Electron Microscopy
Electron microscopy is a high-resolution imaging technique capable of visualizing individual particles and the particle size distribution of ultrafine nanopowders. Scanning electron microscopy (SEM) can provide magnifications of up to 100,000x with the ability to detect particles down to 10 nm. Transmission electron microscopy (TEM) can reach magnifications of 1,000,000x and detect particles down to 1 nm. These microscopes offer the highest level of resolution and accuracy and are best suited for academic research purposes.
