VSP-G1 Nanoparticle Generator (VSP-G1) is a user-friendly, table-top product that allows the user to produce nanoparticles of the desired material in a controlled way. The production of nanoparticles takes place in the gas-phase and is based on a physical process, namely spark ablation. The process is reproducible, occurs at ambient temperature and pressure, and requires only a pair of (semi)conductive electrodes as the source for pure, surfactant-free nanoparticles. With safety, simplicity and automation being core features of the VSP-G1, our systems are easy to operate and require minimal training.
