The VSP-G1 Nanoparticle Generator, from VSParticle, provides a platform for generating contaminant-free, size-tuned nanoparticles in an automated, controlled, and repeatable way. Utilizing spark ablation technology, nanoparticles are produced in the gas-phase under ambient temperature and pressure via a purely physical process free of solvents. Nanoparticles can be produced from any conductive or semiconductive material. By adding a small amount of oxygen to the flow, oxide nanoparticles can also be generated.
