Aerosol Generators and Dispersers

Reliable aerosol generation is essential for defensible experiments. From liquid atomizers to powder dispersers, these sources deliver particle challenges with controllable size and concentration, enabling researchers to evaluate instruments, filters, and processes under reproducible conditions.

Generator types:

• Atomizers and Nebulizers: Produce droplets from liquid suspensions; downstream dryers convert droplets to solid or semi-solid particles.
• Powder Dispersers: Deagglomerate and suspend dry materials with controlled flow and mixing to achieve stable output.
• Salt and Oil Sources: Provide well-behaved reference aerosols for calibration and performance checks.
• Specialty Generators: Support unique chemistries or volatile precursors for advanced materials work.

Applications:

• Filtration Testing: Challenge media with known size distributions to characterize penetration and loading behavior.
• Instrument Checks: Feed reference aerosols to SMPS, OPCs, and aerodynamic sizers for routine verification.
• Inhalation and Exposure Studies: Deliver repeatable aerosols at target concentrations and flows.
• Process Development: Simulate production conditions to refine capture, ventilation, or synthesis parameters.

Best practices:

• Sample Conditioning: Use dryers, neutralizers, and mixing manifolds to stabilize size and charge distributions.
• Concentration Control: Employ dilution systems and feedback to keep detectors in optimal ranges.
• Media Compatibility: Match materials and wetted components to your chemistry to avoid contamination.
• Documentation: Record flows, temperatures, and compositions to support method traceability.

Integration:

• Pair generators with classifiers, DMAs, and spectrometers to build end-to-end test benches.
• Use common fittings and modular manifolds for rapid reconfiguration between studies.
• Leverage data platforms to synchronize generation setpoints with measurement timelines.

With the right generator and accessories, laboratories can shorten setup time, improve repeatability, and produce data that stands up to scrutiny. Our specialists can help you select sources and conditioning modules tailored to your size range, material properties, and regulatory landscape.
