MAGIC 250 - Aerosol Devices

MAGIC 250 CPC

Water-based Condensation Particle Counter
by Aerosol Dynamics Inc.

Purpose

The new MAGIC™ CPC uses a patented, three-stage “moderated” condensational growth system to enlarge particles as small as 5 nm into droplets that are easily detected optically.

Applications:

Environmental air quality studies – especially useful for distributed monitors
Mobile studies in vehicles, aircraft, aboard ships, on drones and bicycles!
Indoor air quality monitoring
Health effects and epidemiology studies
Workplace monitoring for nanoparticles
Can leave unattended for 7 days or more, in most environmental conditions (with large bottle)

Features

light-weight, portable

lower threshold <6 nm

motion-tolerant, may be shaken, tipped, or jostled

tolerates inlet pressure variations

battery operable for ~ 8hrs.

Specifications

moderated

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. The MAGIC CPC's unique feature unique feature is to capture the water vapor needed for supersaturation internally, eliminating the need for internal water reservoirs.
