Seed Aerosol Generators

Seed aerosols underpin experiments where controlled particle growth and classification are essential. By providing repeatable condensation nuclei, these generators support investigations into nucleation kinetics, hygroscopic growth, and coating processes. The result is stronger data integrity and better agreement between lab tests and models.

Applications:

• Cloud microphysics and atmospheric chemistry studies
• Hygroscopic growth and supersaturation experiments
• Mobility-based sizing with DMA/SMPS systems
• Coating and functionalization process development
• Calibration checks for CPCs and related instruments

Technical Benefits:

• Stable Output: Maintain consistent seed concentrations for long experiments and chamber work.
• Material Flexibility: Generate seeds from common salts and other compatible precursors.
• System Compatibility: Integrates with neutralizers, DMAs, CPCs, and impactors for end-to-end workflows.
• Tunability: Adjust concentration and conditions to target desired nucleation and growth regimes.

Best Practices:

• Use a neutralizer to help reach a near-equilibrium charge state prior to mobility classification.
• Monitor RH, temperature, and flow for consistent growth conditions.
• Validate seed size and concentration with SMPS/CPC measurements.
• Record operating parameters to streamline replication across sites or campaigns.

Selection Considerations:

• Seed material and purity requirements
• Target size distribution and concentration
• Integration with chambers, DMAs, and CPCs
• Maintenance, consumables, and cleaning protocols

Outcome:
Seed aerosol generators support method development and model validation, helping teams test hypotheses faster and align results across instruments and facilities. TSI can help configure a system that fits your material choice, growth conditions, and measurement stack.
