Integrated Droplet Activation, Separation and Analysing System (iDASA-200)

Integrated system incorporating a dual column droplet activation chamber with Particle separator, Bio-aerosol sensor and Single particle soot spectrometer.

Droplet Activation Chamber with Particle Separator – Activation of CCN particles at constant supersaturation maintained in a 50-cm high column with continuously wetted walls & a longitudinal thermal gradient; sizing of the activated droplets using an optical particle counter.

Bio aerosol Sensor – Particle size determined by light scattering

Single Particle Soot Spectrometer – Single-particle laser incandescence; Particle number distribution as a function of particle size
