The SPG produces a stable and high concentration solid aerosol at the touch of a button

Wouldn’t it be nice if every time you went to use your aerosol generator, you could be guaranteed of its output concentration and size distribution? For years, it has been a challenge to reliably produce very high concentrations of solid aerosol particles, used in the calibration of CPCs (ISO 27891:2015), PMP (VPR systems, PN-PEMS), filter penetration tests, mask testing, emissions studies, air quality studies, and as a reliable and quantified seed aerosol for complex experiments. This time is over now.
