TSI Model 8108 consists of two parts: a generator column and a control box. The generator column includes a spray nozzle, drying cylinder, and electronic air ionizer (a non radioactive aerosol-charge neutralizer). The control box contains an air-pressure regulator, air filter, peristaltic liquid pump, heater, flow meters, and ionizer power supply. The Model 8108 is designed for long-term, stable operation. When powered up, the generator sprays salt droplets into the top of the drying cylinder. The spray nozzle is easily accessible and can be removed from the drying cylinder for cleaning. The large volume inside the cylinder allows a residence time sufficient enough to dry the aerosol. Heated and ionized dilution air injected from the base of the cylinder aids in this process. The dilution air mixes and dries the droplets thoroughly to form solid salt particles, which exit the cylinder at the base of the generator column. Because there are no bends in the flow path, the aerosol can be directed into your test duct with minimal particle loss.
