    KFMT/ Fast Condensation Particle Counter FCPC3650


    The Model 3650 Fast Condensation Particle Counter (FastCPC) pushes aerosol nanoparticle measurement performance to new heights. Using the classical approach of enlarging particle size through condensational growth from a supersaturated alcohol vapor, particles as small as 1.9 nanometers grow into micron-sized droplets that are individually counted with a laser droplet sensor. Vapor-diffusive, laminar-flow operation provides a stable detection efficiency.
    The FastCPC’s compact package includes internal sheath and transport pumps with critical orifice flow control. A patent-pending parallel-plate flow geometry shortens the aerosol flow path for faster response time and lower diffusion losses.
    A robust active working fluid transport system reduces flooding and reliability problems common with competing products. With no internal alcohol reservoir, the instrument is more tolerant to tipping, vibration, and rapid pressure fluctuations at the inlet making it suitable for applications in mobile transportation studies.
    With faster response than any competing CPC on the market, the FastCPC is the ideal detector for rapidly changing aerosol systems and electrical mobility size distribution measurements.
