Aerosol particles dispersed by nebulization, combustion, or powder dispersion are usually electrostatically charged. For effective transport and for instruments that operate on an electrostatic principle, such aerosols must be properly conditioned.
TSI Aerosol Neutralizers use a radioactive source (Kr-85 or Po-210) to perform this function. The radioactive source ionizes the surrounding atmosphere into positive and negative ions. Particles carrying a high charge can discharge by capturing ions of opposite polarity. After a short time, the particles reach charge equilibrium such that the aerosol carries a bipolar distribution.
The Model 3012 Aerosol Neutralizer is designed for general-purpose applications with flow rates up to 50 L/min.
The Model 3012A Aerosol Neutralizer has five times the activity of the Model 3012.
The Model 3054 Aerosol Neutralizer is intended for use with TSI Model 3450 Vibrating Orifice Aerosol Generators.
The Model 3054A Aerosol Neutralizer has twice the activity of the Model 3054.
The Model 3077 Aerosol Neutralizer is offered for general-purpose applications involving moderately charged aerosols or low flow rates.
The Model 3077A Aerosol Neutralizer has five times the activity of the Model 3077.
The Model 348002 Aerosol Neutralizer is offered for use with our Model 3480 Electrospray Aerosol Generator.
TSI holds a Nuclear Regulatory Agency (NRC) General License for the neutralizers under which the user of device is listed as a “General Licensee.” This is why we require the end users name and address when a 3071A is purchased. There are no other license requirements from the (NRC), but their may be additional state, local or institutional license requirements. The user is responsible for checking for these.
