Nanoparticle

In a CPC the nanoparticles are enlarged

via nucleus condensation.

The sample air passes through a heated

saturator where it is enriched with Butanol.

It is then cooled in the Condenser, where

the now supersaturated vapour condenses

on the particles that act as condensation

nuclei.

The resulting droplets are large enough to

be detected via optical light scattering.

Single Nano Particle Counters

Nano CPC Series 5.400

Highlights

• Counts particles as small as 4.5nm

• Real time updates (1 Hz)

• Wide concentration range

up to 107/cm3

• Portable with integrated battery

• Easy to use

• Additional analog inputs for

climatic sensors

• Integrated butanol tank

Applications

• Mobile aerosol studies

• Nanotechnology process monitoring

• Health effect studies

• Basic aerosol research

• Filter testing

• Particle growth studies

• Environmental & climatic studies

• Inhalation & exposure studies

• Engine exhaust studies

For long-term measurements we offer our CPCs with durable external pumps.

Problem II :

How to determine the particle size?

Sizer - DMA

Nano Particle Sizer - DMA

GRIMM

Vienna Type U-DMA:

Designed for:

- Maximum flexibility (all parts exchangeable)

- Highest resolution

- Lowest diffusion loss

- Controller + HV-module integrated

- Up to 255 channels / scan

- Temperature and pressure sensors integrated

*designed by George Reischl,

Exp. Physics, Univ. Vienna, 2004

SMPS+E = DMA + DMA-Controller + FCE + SoftwareWhen combined with a DMA a Faraday Cup Electrometer (FCE) is used to obtain a Scanning Mobility

Particle Sizer (SMPS+E) for fastest time resolved measurements with the following advantages:

• absolute and fast counting with T10-90 = 88ms per channel

• no size limit (< 0.8 – 700 nm)

• huge concentration range (600 p/cm3 to 100,000,000 p/cm3)

• pressure range 400 to 1,100 hPa
