The outlet of the switching valve leads to the saturator end cap where the flow splits A flow rate of 0 35 liters per minute enters the saturator and passes through the condenser nozzle and sensing volume The remaining flow passes through the excess airline and is recombined with the sampled flow down stream of the sensing volume The PORTACOUNT PRO sensor consists of a saturator condenser and optical elements The saturator is lined with an alcohol soaked wick A thermoelectric device is mounted between the saturator and condenser which cools the condenser and heats the saturator After passing through the saturator the aerosol now saturated with alcohol vapor enters the condenser tube The alcohol vapor condenses on the particles causing them to grow into droplets The droplets then pass through the nozzle and into the sensing volume as depicted in the schematic diagram below The focusing optics in the sensor consists of a laser diode and a series of lenses that focus the laser light into a sensing volume just above the nozzle 76 Appendix B Each particle passing through the sensing volume scatters light The light is collected by the receiving optics and focused onto a photodetector The photodetector generates an electrical pulse from the scattered light as each droplet passes through the sensing volume The particle count is determined by counting the number of pulses generated during a given time period Knowing the particle
