It's time to make your own nanoparticles!


Nanoparticles at the touch of a button

At VSParticle, we believe operating any device should be straightforward. Despite the complexity of the spark ablation process, the VSParticle 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 alter the particle size and production rate. Depending on the material, carrier gas flow and device settings the G1 produces nanoparticles with a mean primary particle diameter between 1 and 20 nanometers at rates up to 20 miligrams per hour.


Chemical free production

The spark ablation process used in the VSParticle 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 recycled by passing it through a filter and used again, minimizing the environmental impact of the process.


Supported materials

Spark ablation is a versatile technology that works with a wide variety of materials, including metals (e.g. silver, copper, gold, platinum, tungsten or nickel), semiconductors (e.g. silicon) and carbon. The VSParticle G1 has two electrodes, so that nano mixtures of two (previously immiscible) materials are easily accessible as well.

Custom electrodes

Depleted electrodes, or do you want to switch to a different material? Simply dismount the reactor unit, unlock the clamps and mount the new electrodes. The VSParticle electrodes have a durable threaded design, making their interchangeability effortless. Various electrode materials are available through VSParticle. Find out more about the possible electrode materials in our Technology section.

Output stability

To get a constant output of nanoparticles at a specific size, it is critical that each spark carries the same amount of energy and takes place under the same conditions. But as electrode material is evaporated during the production of the particles, the distance between the electrodes increases. At the same time, the heating up of the electrodes causes the material to expand. These effects thereby alter the size of the gap that needs to be bridged by each spark, resulting in irregularaties. The VSParticle G1 features a unique motorized control system that counters both effects and keeps the gap between the electrodes constant to give you consistent nanoparticle output, spark after spark.

Nano-safety

Safety is a big concern when working with all kinds of nanoparticles, as potential health effects are still poorly understood. Therefore, the VSParticle G1 is operated as a closed loop system and features a detachable reactor unit. Simply move the reactor unit from the system into the safe environment of a fumehood to clean the reactor, switch electrodes or change flow configuration. Two alignment pins and attachment screws ensure that the reactor unit can be quickly and easily remounted on the device.


Other features

  • Electrodes can be replaced by user.
  • Materials can be mixed at the nanoscale level by using electrodes of different materials.
  • Highly pure nanoparticles are produced in a reactor made of inert materials, therefore contamination from chemicals/surfactants or precursors is avoided.
  • The system output consists of a gas stream filled with particles, thus there are no polluting by-products formed during production.
  • The reactor is easily customizable to allow cross flow, co-flow, through flow (standard), and combined configurations.
