Supermicron-Capable Particle Sizer Spectrometers

When research demands size-resolved data beyond the submicron regime, supermicron-capable spectrometers provide the required range and response. Using aerodynamic or time-of-flight techniques, these systems infer particle size from velocity or flight time through a controlled flow field, producing real-time distributions across the micrometer domain.

Where they add value:

• Inhalation and Exposure Studies: Resolve coarse fractions that influence deposition behavior and exposure assessment.
• Environmental Monitoring: Track dust and bioaerosol size distributions near sources or in controlled chambers.
• Filtration and Separation: Quantify size-dependent capture for filters, cyclones, and separators.
• Powder Processing: Evaluate dispersibility, deagglomeration, and handling conditions for dry materials.

Performance highlights:

• Real-Time Output: Capture dynamic changes during process upsets, filter loading, or environmental shifts.
• Broad Range: Address particle sizes that optical counters may miss or undercount in specific matrices.
• Stable Measurement Physics: Aerodynamic sizing offers a direct link to particle behavior in flows.
• Integration Ready: Pair with mobility sizers, OPCs, and gravimetric samplers to span nano-to-coarse regimes.

Best practices:

• Sample Conditioning: Employ dryers, neutralizers (when applicable), and isokinetic probes for representative sampling.
• Flow Alignment: Maintain proper nozzle, sheath, and acceleration conditions to support sizing accuracy.
• Calibration: Use traceable size standards and periodic checks to validate instrument response.
• Data Strategy: Harmonize binning and reporting with other instruments for seamless multi-modal analysis.

These spectrometers help R&D teams connect coarse-mode dynamics with nano and fine modes, creating a complete picture of aerosol behavior. From pilot lines to field deployments, the combination of rugged hardware and flexible data interfaces supports confident decision-making.
