Water-Based Condensation Particle Counter

MAGIC is our most recent commercial water-based condensation particle counter. It is portable, battery operable, and can be tipped, or jostled. MAGIC is sold through Aerosol Devices Inc.

What it does:

MAGIC measures the number concentration of airborne particles larger than 5 nm in diameter..

How it works:

The acronym stands for moderated aerosol growth with internal water cycling. Ultrafine particles are enlarged by water condensation to form micrometer-sized droplets that are detected optically. MAGIC’s unique feature is to capture the water vapor needed for supersaturation internally, eliminating the need for internal water reservoirs.
