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 offers aerosol neutralizers that 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.
NEW! TSI now offers a nonradioactive alternative to traditional neutralizers with the Advanced Aerosol Neutralizer (AAN) Model 3087. Fully compliant with US FDA, CDRH* standards, the Model 3087 (U.S. Patent 7,796,727) provides an attractive new option, with sizing performance virtually identical to TSI’s Aerosol Neutralizer Model 3077A.

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.
