♥ Epoch-making system that can measure ultrafine particles in nanometer size.
♥ Please feel free to ask for custom-made systems as well as our standard systems.
1.A few reasons to use DMAs ?
• Size selection is needed to extract functions of ultrafine particles.
• Nano-particle formation must be monitored for efficient semiconductor manufacturing.
• Nano-particle measurement in combustion gas has become possible using DMAs.
Classification section & Faraday cup electrometer
In conventional optical methods, size measurement in 1~100nm is practically impossible.
Measurement in nanometer size in the key technology for the development of new processes and new materials.
• DMA utilizes particle electric mobility dependence on size.
• DMA can classify and measure particles in nanometer to submicron range.
• DMA can measure minute gas-borne particles.
