Device for charging aerosols and particles, ozone generation based on corona effect. Includes high DC voltage source.
Features.
- Unipolar charger for very small nanoparticles (<30nm) hardly chargeable by bipolar chargers.
- No radioactive source.
- High charging efficiency (30% for 10nm particles).
- Reversible polarity +/- Ion current >100pA.
- Stability ~ 1% over 1hour.
- Characterized for different working conditions.
- Characterized to prevent filamentary discharge that erodes electrodes and generates vapour.
- Current limited to prevent arcing
