A11 nCNC-system

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 Airmodus 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 Airmodus 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.

Counting and detecting individual aerosol particles down to molecular sizes

Airmodus technologies are filling the gap between aerosol particle size distribution measurements and gas phase monitoring.

Nucleation researchers can observe clusters of molecules and the nucleated particles when they are as small as 1 nm. And, learn further about the growth of the particles using the activation spectra of 1–4 nm particles.

Airmodus A10 PSM

A10 PSM grows nano-sized aerosol particles into sizes that can be detected with a standard CPC. Particles as small as 1 nm can be counted.

  • Study and monitor particles smaller than the detection threshold of any CPC.
  • A10 PSM can be combined with any CPC.

Airmodus A11 nCNC

A11 nCNC is a complete system consisting of a particle size magnifier, a particle counter and operation software. It can be used with fixed cut-off to count total particle number from the cut-off size to 1 micron

  • Indicator for the presence of very small aerosol particles.
  • The cut-off can be selected by the User.

A11 nCNC in scanning mode gives the activation size distribution for 1–4 nm particles.

  • Learn about the characteristics and dynamics of the 1–4 nm particles.
  • The A11 operation software contains all the necessary inversion algorithms to define the activation spectra for the nucleated aerosol particles.
