Why Particle Size Is Important to Product Materials?
"Particle Size Analysis" is an important process that must be applied to the research and production, especially in chemical industries, food industries, biotechnology industries, and pharmaceutical industries. This analysis process is used to realize the particle size and its distribution of a substance or material itself. Although the particle size is a physical condition, however, it not only affects physical properties (such as appearance, density, color, etc.), but according to the the compositions of material, it may also affect its chemical properties (such as reaction speed, effectiveness, and so on).
In order to meet the requirements of particle size analysis in different industries, there are various particle size analyzers in the market, which are designed based on different technologies. These instrument tool are used to analyze micro particles or raw materials in different range of sizes. Understanding the impact of particle size distribution in granularity and applications of the product, will be useful to determine its applicability and effectiveness.
In this article, we will discuss about the influences of particle size in different conditions, and listed below for your reference.

Principle of Zeta Potential and Its Importance
Principle of Zeta Potential
Zeta Potential is used to describe the potential of nano-level colloidal particles on its slipping plane, with the unit millivolts (mV) in general. Since the slipping plane of particles is the boundary separating itself and bulk fluid, by measuring the zeta potential, one can have the distance from the surface of particle to slipping plane. This distance constitutes the thickness of the electric double layer, which is the thickness of the positive and negative layers of ions on the interface between the particles and the fluid. The thickness can be used to determine the characteristics and stability of the colloid.
Thermal Safety Test Methods
Thermal safety test is an important part of the material development process. The electronic products today are especially light, thin, and small today with longer battery life. The energy density in the energy storage devices (batteries, chemical fuels) are getting higher and higher. When the devices encountered thermal runaway combustion, they would often cause a certain harm to the living bodies and environment. Coupled with the rise of consumer awareness today, manufacturers often need to bear joint liabilities, even huge compensation to pay. The material manufacturers or product manufacturers have to be careful about the safety of their products.
Thermal Analyzer in Characterization of Foodstuffs
Moisture, and other natural compounds present in the foodstuffs (milk, eggs, meat, vegetables, cereals) are generally heat sensitive. Heating these foodstuffs often changes the physical properties microbiological and sensory characteristics. Determinations of the "time-temperature" parameters is useful in maintaining the physical stability or long-term storage and safety of food. For example, delay the lipid oxidation in butter, hindering of starch staling in bread, or fat blooming in chocolate, or phase separation in sauces.
These are the areas of focus for food-engineering researchers, who rely on differential scanning calorimetry (DSC) to understand the properties of food raw materials from the perspective of thermodynamic dynamics of non-equilibrious reactions, or interactions of unidentified chemical molecules.
