Monodisperse Generators

Monodisperse generators are foundational tools for aerosol science, enabling size-specific experiments that drive reliable conclusions. By combining controlled atomization with classification, these systems produce aerosols with a narrow geometric standard deviation that supports exacting R&D needs.

Applications:

• Calibration and verification of SMPS, CPCs, OPCs, photometers, and spectrometers
• Filter media testing and full-system filtration efficiency mapping
• Inhalation exposure studies requiring known particle sizes
• Particle deposition, transport, and diffusion research
• Materials science experiments where particle size influences surface interactions

Technical Benefits:

• Tight Size Control: Produce particle sizes across nanometer to micrometer ranges with high repeatability.
• Stable Output: Maintain concentration stability during extended runs, supporting long-duration sampling and statistics.
• Flexible Materials: Generate aerosols from salts, oils, and other compatible solutions to match your study requirements.
• System Integration: Works smoothly with neutralizers for charge equilibrium and with classifiers and counters for closed-loop workflows.

Best Practices:

• Use a bipolar neutralizer to help achieve near-equilibrium charge distributions before classification.
• Pair with a DMA/SMPS for feedback-based size selection and real-time verification.
• Monitor flow rates and solution concentration to maintain consistency across runs.
• Document set points and environmental conditions to support reproducibility and peer review.

Selection Considerations:

• Target size range and resolution
• Required concentration and duration of output
• Compatibility with existing SMPS/OPC/CPC systems
• Cleaning, maintenance, and consumables

Outcome:
A monodisperse source strengthens method development, accelerates instrument validation, and supports comparative studies across teams and sites. Talk with a TSI specialist to match a generator to your target size range, material, and measurement workflow.
