UF-CPC System

Determination of number concentration of ultrafine aerosols from 4 to >3,000 nm by condensation to 106particles/cm3in single count mode

Condensation particle counter for number concentration up to 105particles/cm3 (single count mode) and 107 particles/cm3 (photometric mode)
Condensation particle counter for number concentration up to 2 • 106 particles/cm3 (single count mode)
Condensation particle counter for number concentration up to 104 particles/cm3 (single count mode) and 107 particles/cm3 (photometric mode)

One of the outstanding features of the UF-CPC series is its option of using different condensation fluids in the same device: 1-butanol (standard) or distilled water. This UF-CPC, with its innovative method of supplying the condensation fluid, is patent-protected. The condensation process makes the nanoscale particles measurable.

In addition to quantity, the UF-CPC measures condensed particles' droplet size, thus providing additional information about the condensation process. With the UF-CPC series, concentrations of up to 106 particles/cm3 can be measured in single-count mode with an accuracy of 5 % and – in photometer mode – up to 107 particles/cm3 with an accuracy of 10 %.

In combination with an upstream classifier, the DEMC, the size distribution of an aerosol can be determined quickly and reliably.
