FAST CONDENSATION PARTICLE COUNTER　MODEL 3650 (FCPC)

FAST CONDENSATION PARTICLE COUNTER
MODEL 3650 (FCPC)

A thermally diffusive, laminar-flow condensation particle counter.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.

FEATURES

  • Fastest response time of any commercially available condensation particle counter.
  • 50% response time ~ 80 ms
  • 10-90% response time ~ 35 ms
  • time constant (τ) ~ 20 ms
  • 50% detection efficiency at 2.4 nm.
  • Relatively high 300 ccm sample flowrate.
  • Reliable active working fluid transport system avoids flooding-related failures.
  • Compact design.
  • Vapor diffusive, laminar flow operation provides a stable detection efficiency
