Particle size analysis is a technique used to study the size distribution of particles in a sample. It is a vital analysis technique in many industries, such as pharmaceuticals, food, chemical, and environmental due to the importance of controlling particle size for the product's performance. However, the accuracy of the particle size analysis results depends significantly on the instrument's precision and how well the sample preparation and measurement process is executed. In this blog post, we will discuss the factors that can affect the accuracy of particle size analysis.
During the transportation process of powder, it is necessary to avoid stacking, as stacking can affect the fluidity of the powder. Stacking can be avoided by installing slopes, increasing transportation pipelines, and other methods.
The preparation of SEM nano powder samples usually requires the following steps:
These nano powders can improve the biocompatibility, mechanical properties, bioactivity and degradability of bioceramics by adjusting the particle size and morphology, making them more suitable for biomedical applications. Of course, the specific selection of the types and applications of nano powders should take into account the characteristics of materials and specific application scenarios.
The crystal structure of nano iron oxide is hexagonal, and the lattice parameters change with the decrease of particle size. When the particle size is large (usually larger than tens of nanometers), iron oxide exhibits a typical α- The Fe2O3 structure, also known as hematite structure, is red in color. This is because typical α- The Fe2O3 structure has a high reflectivity for visible light, absorbing shorter wavelengths (blue-green) in visible light, leaving only longer red wavelengths observed.
Chemical Total Element Analysis (ICP-MS) is a widely used instrument technology in the field of chemical analysis. It is developed based on inductively coupled plasma mass spectrometry (ICP) technology.
