VSParticle Nanoparticle Generator Accessories

Go from hypothesis to result in the same day

VSP accessories provide research scientists with flexibility and speed in sample preparation. Simply attach the desired deposition accessory onto the outlet of the VSP-G1 to collect nanoparticles in one of three methods: diffusion, filtration, or impaction. Alternatively, connecting the Size Selector to the outlet refines the aerosol stream to a monodispersion, ideal for model catalyst studies. Typical sample preparation times range from a few minutes up to an hour.

Size Selector

Size-dependent catalytic activity screening made simple with VSP-S1

Produce catalytically active nanoparticles in the range of 1-10 nm to study particle size effects and develop clear structure-activity relations. Particles are selected in-line and deposited onto substrates (e.g. MEMS chips for in situ TEM). The automatic preparation of catalytic samples with 0.1 nm size selection resolution enables sequenced sample production in less than a day.
