The NAG offers unparalleled performance and versatility for researchers and industry professionals
Introducing the NanoAerosol Generator Model 3250 by Kanomax FMT—a state-of-the-art pneumatic nebulizer engineered to produce ultrafine aerosols from aqueous solutions or colloidal suspensions. This advanced instrument is ideal for researchers aiming to generate droplets with precise, small size distributions, making it indispensable for aerosol research, nanoparticle analysis, and filter testing applications.
Key Features:
- Ultrafine Droplet Production: Generates droplets with a peak diameter of less than 1 μm, significantly smaller than those produced by conventional nebulizers. This minimizes the influence of non-volatile residue, ensuring high-purity aerosol generation.
- Direct Sample Injection: Utilizes direct injection into the nebulizer without the need for on-line dilution, resulting in a more compact and cost-effective design.
- Clog-Resistant Design: Unlike electrospray methods, the NAG does not require conducting liquids and can handle high-percentage solid suspensions with minimal risk of clogging.
- Integrated Heating System: Features an integral heater and dilution air mechanism to evaporate droplets and lower the dew point, eliminating the need for a separate desiccator.
- Stable Output for Extended Operation: Maintains sample solvent concentration over long-term use, ensuring a stable generated particle size and consistent performance.
Applications:
- Aerosol Research: Ideal for generating nanoparticles with minimal non-volatile residue, crucial for studies requiring high-purity aerosols.

How it works
The NanoAerosol Generator (NAG) uses the same nebulizer design as the NanoParticle Nebulizer (NPN). However, unlike the NPN, the NAG has no on-line dilution capability’ any sample uses direct injection into the nebulizer allowing for a smaller, simpler and less expensive device.
The sample to be nebulized is placed in a pressure vessel. When the vessel is pressurized to 18 psi the particle suspension is delivered to the nebulizer at the correct flow rate for direct injection. The pressure vessel can be replaced with a peristaltic pump that then delivers the sample to the nebulizer at the correct flow rate.
The NAG has been designed for aerosol researchers who wish to produce droplets of a known, small, size distribution. The NAG aerosolized particle size of a 0001% sucrose solution is approximately 13 nm. Unlike electrospray, the NAG does not require a conducting liquid, can handle a very high percentage solids suspension and almost never clogs.
Advantages of the NAG
- Produces significantly smaller droplets than conventional nebulizers minimizing the influence of non-volatile residue.
- Aerosolizes primary particles with reduced potential for agglomerate artifacts.
- Uses pressurized sample delivery for high-purity and low-volume consumption.
- Eliminates the need for a separate desiccator by including an integral heater and dilution air to evaporate droplets and lower the dew point.
- Extends operation time with a highly stable output. Sample solvent does not evaporate over long-term operation maintaining a stable solution concentration and therefore a more stable generated particle size.
