Aerosol Generation System (AGS)

The AGS is an instrument which is simple to use, cost effective and controllable constant output aerosol generation.

Product Description 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, chemically-inert stainless-steel design. The AGS has been successfully deployed at remote climate monitoring sites integrated with the Brechtel HTDMA to allow automatic periodic sampling of AGS-generated particles to validate HTDMA operation during long-term ambient sampling. The optional syringe pump accessory provides ultra-precise output concentration control for applications requiring extremely stable aerosol concentrations. Automation options are also available to allow a user supplied digital control to turn on the AGS and switch instruments to sample the generated aerosol.
