the standard in nanoparticle generation
A table-top, user-friendly nanoparticle generator that is the basis of all VSPARTICLE products. With the VSP-G1, a stable and clean flow of well-defined pure nanoparticles can be generated, without the use of precursors and surfactants. Producing the desired particles becomes as easy as pushing a button.

Material versatility is key to prepare model catalyst samples, VSPARTICLE's technology enables you to change the material easy and fast thanks to the use of electrodes. This allows the creation of particles of bi-metals, nano-alloys or materials that are immiscible in bulk state. Source material is supplied in the form of electrodes. The electrodes work with a click system, making it easy and quick to switch materials.
"For our research in the safety of airborne nanomaterials, VSPARTICLE's VSP-G1 enables us to generate very small particles. We use this both as a reference method, as well as for our research into the distribution of very small nanoparticles in the body after inhalation"
Flemming Cassee - RIVM
"The VSPARTICLE tools enable you to combine different materials together on any substrate, changing their functionalities. At the Smith Solar Lab, we have used VSPARTICLE's machine in different ways, because you can make nanoparticles of different sizes and compositions. They have different optical properties, so you can actually tune which part of the solar light is absorbed by pushing a button. Which is something we have not been able to find in any other technology"
Wilson Smith - Smith Solar Lab TU Delft
"The sample preparation is applicable for a wide range of materials as well as metal nanoparticle sizes. This ensures that valuable time on TEM machines is well used. In addition, tuning particle size with settings prior to deposition allows us to study the size dependency of the metal nanoparticles for a given catalytic reaction. In total, it takes less than an hour to make a sample and the same MEMS devices can be used."
Charlotte Vogt - Debye Institute. University of Utrecht
"The purely physical mechanisms resulting in the formation of particles without chemical reactions leads to pure aerosols that are ideal for the use as model particles for different studies. Furthermore, compared to other aerosol synthesis methods, the spark ablation and especially, the VSP-G1 nanoparticle generator, results in a stable and defined production even over longer time spans, which is important to draw meaningful conclusions."
Weber group - Institute of Particle Technology, Clausthal
“..making such new materials is challenging for us because very often we need to actually use very difficult chemical synthesis methods and we also produce a lot of unwanted chemical waste then. By using the nanoparticle generator (VSP-G1) and the size selector (VSP-S1) we can now actually just press a button and make these materials without producing any chemical waste so this makes our experiments much easier.”

With the VSP-G1 you can use any kind of (semi)conductive material for your nanoparticles and use argon, nitrogen or air as a carrier gas.The VSP-G1 uses two electrodes as base material to generate sub 20 nm particles. All solid (semi)conductive materials that can be processed into electrodes can be used in this device.
Spark ablation technology is a physics based process, generating pure particles in a very controlled setting, without the use of chemicals. Our co-founder Andreas Schmidtt-Ott invented the technology in 1988 and was then developed into an easy to use device. The spark ablation process used inside the 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.

How can I mimic real life situations with the system?
The VSP-G1 is worldwide the only device that can make gas-phase atomic clusters and nanoparticles at standard pressure and temperature, for any (semi) conductive material. Furthermore, it is possible to shift the whole size distribution under 5 nm (only primary particles).
What particle sizes can I make?
The primary particle size is 0-20 nm.
What are the current studies conducted with the VSP-G1 in nanotoxicology research?
Currently we are conducting research together with the Dutch Health Institute (RIVM) with Flemming Cassee, who uses the G1 both as a reference method and uses radioactive gold particles to study the biodistribution of clusters in mice. Furthermore, we have projects to determine the toxicity of FeO nanoparticles together with Delft University and carbon nanoparticle toxicity with Roel Schins at the University of Dusseldorf.
How stable is the output?
The VSP-G1 can be tuned and standard deviation can be reduced to below 2% of the output.
What materials are compatible? Can I make oxides and alloys?
The VSP-G1 can be used with any (semi-) conductive material, amongst which carbon, copper and gold. The material is used in the system in de form of electrodes. By adding air to the gasflow, oxides can be made. Learn more about compatible materials here.
The VSP-G1 Metal Aerosol Generator has bench-top dimensions and is designed to fit most lab-tables and fume hoods. If you wish to set it up in your own lab, you can opt for either buying or leasing the nanoparticle generator. It is also possible to work in our lab or let vsparticle provide you with some test samples. Just contact our sales team or complete the contact form to see which option fits your situation and research best.
