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. It is the only commercially available measurement system for determining the size distribution of both neutral and charged 1-4 nm aerosol particles.
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.
How it works
The Airmodus A11 Nano Condensation Nucleus Counter system (nCNC) measures particles as small as 1 nm in diameter. It is a complete system consisting of a particle size magnifier (PSM), a condensation particle counter (CPC) and operation software. Airmodus A11 can be used to measure the total number concentration of sub-micron particles, or to learn about characteristics and dynamics of the 1-4 nm particles in real time.
Airmodus A30 is very compact and portable, and designed to be used standalone.
