Instrument: M55 Mainz COPAS

Name M55 Mainz COPAS
Acronym COPAS-M55
Manufacturer University of Mainz
Operated by Geophysica-GEIE
Operated onboard

Instrument type

Name Condensation Particle Counter (CPC)
Acronym Condensation Particle Counter

Principle of operation

Measured parameter Number concentration of submicrometer aerosol particles
Operating principle

The particles are detected and counted by a simple optical detector after a supersaturation vapor (butanol or water) condenses onto the particles, causing them to grow into larger droplets. The CPC uses a (laser diode) light source, a condensing lense, an internal microprocessor control, volumetric flow control and a front panel display.

COndensation PArticle detection System.
Counts particles between 10 nm and 10 micrometers in diameter. Two channel condensation nuclei counter.
Residual particles, which are not evaporated after passing through the barrier are counted by the COPAS instrument mounted downstream of the CVI inlet.
