Aerosol Generation System (AGS)

Model 9200


The Model 9200 AGS is an ideal tool to generate known composition and size aerosol for laboratory experiments and instrument characterization studies. It delivers constant and controllable aerosol generation in an easy-to-use, stainless-steel design. The AGS has been successfully deployed at remote climate monitoring sites integrated with the Brechtel Model 3002 HTDMA to allow automatic periodic sampling of AGS-generated particles to validate HTDMA operation during long-term ambient sampling.

  • Very constant output atomizer
  • Controllable liquid flow rate
  • Atomizer sprays into a chamber to avoid backup and clogging of sprayed droplets
  • Atomizer sample air flow rate 2-7 lpm
  • In-line desiccant dryer to dry droplets
  • Easy-to-change dryer desiccant
  • All stainless steel construction to avoid chemical artifacts associated with plastics
  • Easily rack mountable
  • Automation options available to control air and liquid supplies to atomizer to switch between ambient and AGS sample inlets


  • Easy to use controls to set desired output concentration
  • Chemical purity through stainless steel design
  • Easy to maintain
  • No clogging of atomizer by design – leading to more constant output
