Aerosol Charge Conditioners
Aerosol charge conditioners (also commonly referred to as aerosol neutralizers) are an essential component of many aerosol research and measurement systems. Aerosol particles generated by nebulization, combustion, or powder dispersion typically carry significant electrostatic charge.
Excessive particle charge can increase particle losses to the walls of sampling and transport systems and influence measurements such as filtration efficiency. For aerosol instruments based on the principle of electrical mobility, particles must first be conditioned to a well-defined equilibrium charge distribution to ensure accurate, repeatable measurements.
Aerosol charge conditioners establish this predictable equilibrium charge distribution before particles enter downstream instrumentation, helping improve measurement consistency and enabling reliable electrical mobility analysis.
Types of Aerosol Charge Conditioners
Aerosol charge conditioners are available in two primary technologies:
| Radioactive Charge Conditioners | Non-Radioactive Charge Conditioners |
|---|---|
|
Radioactive charge conditioners use alpha- or beta-particle emissions from radioactive isotopes to establish an equilibrium charge distribution on aerosol particles. They have long been the industry standard due to their reliability, simplicity, and continuous operation without requiring electrical power. Because they operate passively, they continue conditioning aerosols even during power interruptions. TSI offers a range of radioactive charge conditioners with different source sizes and activity levels to meet the requirements of most aerosol research applications. |
For applications where radiation regulations or handling requirements make radioactive sources less desirable, non-radioactive charge conditioners provide an effective alternative. These systems use electrical power to generate x-rays or high-voltage corona discharge to establish the desired particle charge distribution. Because they operate only when powered, non-radioactive charge conditioners can offer extended service life in intermittent-use applications and typically do not require the special licensing, transportation, or purchasing restrictions associated with radioactive sources.
