Spark ablation technology is a physics-based process, generating pure particles in a very controlled setting, without the use of chemicals. The spark ablation process used inside the VSP-G1 Nanoparticle Generator (VSP-G1) is a purely physical process that only requires electricity, a carrier gas and electrode material to produce clean nanoparticles. No additional chemicals are required for the production or to stabilize the particles in the aerosol.

The produced nanoparticles can be directly incorporated into the next process step or applied in a product by, for example, impaction, electrostatic precipitation, or filtering. This way the unique physical properties of the nanoparticles are directly available in the product. The carrier gas can simply be recirculated, minimizing the environmental impact of the process. The output is a highly concentrated aerosol of pure (metal) nanoparticles suspended in a clean gas at low temperatures (<50 °C).
