Aerosol Neutralizers

Product catalog summary

Overview: The document provides detailed specifications and features of various aerosol neutralizers offered by GRIMM Aerosol Technik. These devices are designed for different applications, utilizing both radioactive and non-radioactive ionization sources to ensure a well-defined charging state of aerosols.

1. Aerosol Neutralizers:

Radioactive Ionization Sources: Includes Am-241 and Ni-63 sources. Am-241 has a nominal activity of 3.7 MBq and a maximum energy of 5.6 MeV, suitable for aerosol flow rates up to 5 l/min. Ni-63 has a nominal activity of 95 MBq and a maximum energy of 66 keV, suitable for flow rates up to 1 l/min. Both are compatible with GRIMM SMPS+C and SMPS+E systems.
Non-Radioactive Ionization Sources: Utilizes soft X-ray and dielectric barrier discharge plasma methods. Soft X-ray sources are available with energy levels of <11 keV or <4.99 keV, supporting flow rates up to 5 l/min. The dielectric barrier discharge plasma method supports a flow rate of 0.3 l/min and is not suitable for use with N2, Ar, or corrosive gases.

2. Technical Specifications:

Am-241 Aerosol Neutralizer: Features include a stainless steel housing, dimensions of 4 x 5.5 x 5 cm, and a weight of 0.55 kg. It has a half-life of 433 years.
Ni-63 Aerosol Neutralizer: Features include stainless steel housing with lead shielding, dimensions of 18 x 6.9 x 6.9 cm, and a weight of 2.5 kg. It has a half-life of 96 years.
Soft X-ray Aerosol Neutralizer: Features include natural cooling, power supply of 100-240 VAC, dimensions of 19.1 x 7.2 x 27.3 cm, and a weight of 11.1 kg.
Dielectric Barrier Discharge Plasma Aerosol Neutralizer: Features include a power supply of 100-240 VAC, dimensions of 18.0 x 6.9 x 6.9 cm, and a weight of 2.5 kg.

3. Key Benefits:

All devices are low maintenance and easy to operate.
Radioactive sources do not require a handling license as their activity is below regulatory thresholds.
Non-radioactive sources have no transport or storage restrictions.

4. Applications: These aerosol neutralizers are optimized for direct connection to GRIMM DMAs and are compatible with GRIMM SMPS+C and SMPS+E systems, making them suitable for a wide range of aerosol measurement applications.
