We utilize a novel technology to disperse uniform dry powder on SEM stubs. The Nebula™ Particle dispenser ensures best sample preparation by obtaining a mono layer of particles avoiding particle clusters while maintaining the structure of fragile particles.
Stationary bulk solids such as dry powder or granules (aggregate material) will partly form agglomerates. The strength of these non-material bonds depends on particle size and the underlying attractive forces. Depending on material properties, surface condition, residual moisture, and particle size, it may be Van der Waals forces, capillary forces, or electrostatic and magnetic forces of attraction for example that act in forming bonds. The basic rule is that the smaller the particles, the greater the tendency to bind.
We can prepare many types of powers and nanoparticles for SEM and EDS analysis. This can be combined with particle morphology analysis, foreign particle detection, and a variety of applications from Additive Manufacturing QC to failure analysis, to predictive maintenance applications.
