Particle Sizers

Particle size drives aerosol behavior, health relevance, material performance, and process outcomes. Particle sizers give researchers the resolution and range to understand these relationships, enabling better design, validation, and optimization. Technologies include electrical mobility (commonly paired with CPCs for SMPS systems) for nanoparticles, optical scattering for micron-scale particles, and aerodynamic sizing for particles where inertia and shape matter.

Key benefits:

• Broad coverage: Combine techniques to span a few nanometers through tens of micrometers.
• High resolution: Resolve fine distribution features that inform nucleation, growth, and aggregation studies.
• Time-resolved insights: Track dynamic processes during synthesis, combustion, or environmental events.
• Integration-ready: Interfaces for coupling with generators, classifiers, diluters, and deposition systems.

Applications:

• Nanomaterial synthesis and process control with size-based tuning.
• Filtration and separator performance mapping across size fractions.
• Engine and combustion research to understand formation and aging.
• Environmental and indoor air studies that link size to exposure metrics.
• Pharmaceutical aerosol and inhalation research, where aerodynamic size impacts deposition.

Selection factors:

• Required size range and resolution for your scientific objectives.
• Sampling flow and aerosol conditioning needs, including neutralization and dilution.
• Time resolution and data processing requirements for transient events.
• Software features for distribution analysis, reporting, and collaboration.

Best practices:

• Calibrate on a regular schedule and verify sizing with traceable standards where applicable.
• Standardize sampling lines and conditioning to support comparability across sites.
• Document instrument settings and data workflows to streamline peer review and publication.

With the right particle sizer, teams can move quickly from observations to insights, translating size distributions into decisions that advance research and product development.
