A11 Nano Condensation Nucleus Counter

Airmodus Nano Condensation Nucleus Counter (nCNC) (model A11)

Airmodus A11 nano Condensation Nucleus Counter (nCNC) is the only commercially available measurement system for determining the size distribution of both neutral and charged 1-4 nm aerosol particles.

The A11 nCNC-system, consisting of the A10 PSM and the A20 CPC, helps you to detect and monitor the very smallest aerosol particles, down to 1 nm in size. With the A11 you can observe the temporal variations of the number of sub-3 nm particles that are not visible with other methods. The A11 nCNC can be used to measure the activation size distribution of 1-4 nm particles, as well as the total particle number concentration of sub-micron aerosol particles.


• Detect both electrically neutral and charged particles
− No charger or DMA in the system

• Sensitivity down to 1 nm
− High detection efficiency compared to charge based methods – read more

• The cut-off can be selected by the user
− Cut-off can be changed between 1-4 nm

• Real time data inversion
− Easy to use A1X operation software for system control and data inversion
