Nanoparticle Generator for all Conductive Materials

The VSP-G1 nanoparticle generator provides customers with the possibility to perform innovative research within the realm of nanomaterials without the restrictions of common generation techniques and materials.

Material Versatility

Mix and Match Metals - The VSP-G1 uses two electrodes as base material to create sub 20 nm particles. Below 20 nm, quantum effects of nanoparticles can be employed for all kinds of applications. All solid (semi)conductive materials that can be processed into electrodes can be used in this device. This allows for the creation of particles of nano-alloys, bi-metals or materials that are immiscible in bulk state.

Easier, Faster and Reproducible Production of Nanoparticles

The current methods to create nanoparticles are complex, which makes them time consuming and restricted to just a few materials. With the VSP-G, Researchers can bring back months of work to just a matter of hours or days:

  • Fast: the VSP-G1 offers unproblematic interchangeability of electrode material
  • Easy: The VSP-G1 is controlled by just three buttons. The first one serves as on/off switch and emergency stop, while the other two are used to modify the particle size and production rate. The VSP-G1 is operated at standard pressure and room temperature.
  • Reproducible: After the ideal settings are defined, users will have nothing that stops them from reproducing it with the VSP-G1.

Very Small Particles

Output distribution of particles between 0-20 nm - Creating large particles at high concentrations is easy, but making minuscule particles at high concentrations is one of the most demanding tasks in material science and aerosol research. The VSP-G1 offers high output of very small particles, starting from atom clusters of a few atoms.

Ultra-Stable and Reliable Aerosol Output

Ultra-Stable and Reliable Aerosol Output

Stability of 98% in long term experiments - Sophisticated experiments in material science and aerosol research demand a very stable and extremely reproducible output of sub 20 nm particles.

The VSP-G1 has an extremely reliable production output, with an average stability up to 98%. This will help to accelerate one’s research and increase reproducible results over long term experiments.

No Chemicals Needed

The spark ablation process used in the VSP-G1 is a purely physical process that only requires a carrier gas, electricity and electrode material to create clean nanoparticles. No extra chemicals are required for the production or to stabilize the particles in the aerosol. The manufactured nanoparticles can be straightaway added into the subsequent process step or applied in a product by, for example, electrostatic precipitation, impaction or filtering.

This way the unique physical properties of the nanoparticles are directly available in the product. The carrier gas can merely be recycled by sending it through a filter and used again, decreasing the environmental impact of the process.

Use of Any (Semi-)Conductive Material

Spark ablation is a versatile technology that works with a wide range of materials, including metals (for example tungsten, copper, silver, gold, platinum, or nickel), semiconductors (for example silicon) and carbon.

In the table below, elements emphasized in green are those that have been found to be well-matched with spark ablation. Other elements for which information is available are presented in black while elements that may be used in the spark ablation process (for example as carrier gas or modifier) are displayed in green.
