aerosol generatorAerosols are generated by acidification or evaporation of substances, and then transported to the testing environment through a precise airflow control system. The generated aerosol particles are evenly distributed, ensuring stable and adjustable concentration. Users can set the concentration range (usually 10 μ g/L to 100 μ g/L) by adjusting the airflow and nozzle number.

　　aerosol generatorClassification:

Classified by generating medium

Dust type: such as TOPAS SAG420 dust generator, which uses servo drive technology to achieve precise feeding and forms suspended particles through compressed air diffusion.

Liquid type: Includes Collison type and Laskin type atomizers. The former can be sterilized at high temperatures and supports 50-500ml sample cups, while the latter can generate 10-100 μ g/L concentration oil mist.

Salt spray type: such as AGK2000 salt spray generator, using anti crystallization nozzle technology, can generate salt spray with particle size of 5nm-15 μ m, suitable for the pharmaceutical and chemical industry.

Classified by technical principles

Pressure spray type: pressure is generated by compressing gas or liquid to spray liquid from nozzle to form small droplets.

Ultrasonic spray type: use high-frequency acoustic energy to decompose the liquid into small particles.

Evaporative spray type: vaporize the liquid by heating it to produce small solid particles.
