Aerosol Effective Density Measurements for Spherical Particles, 50–500 nm

Data from a 2026 study investigating key parameters for measuring effective density of low-volatility spherical particles. The dataset, authored by M. Kiasadegh, includes measurements from three tandem instrument setups using a DMA, CPMA, and AAC, with mass set points from 0.05 fg to 5 fg and aerodynamic diameters from 50 nm to 500 nm. Results detail the impact of instrument resolution, flow mode, and characteristic scan time on measurement accuracy and operational range.

Use Cases

• Optimizing instrument resolution settings for effective density measurements based on the described trade-offs between accuracy and range.
• Calibrating particle classifiers using the described method of calibrating with Santovac particles.
• Comparing the performance of scanning downstream classifiers (SMPS vs. SASS) under different aerosol flow rates (0.3 L/min vs. 1.5 L/min).

Strengths

• Specific mass set points ranging from 0.05 fg to 5 fg provide a defined measurement scale.
• Aerodynamic diameter set points cover a range from 50 nm to 500 nm.
• Data compares three distinct tandem instrument configurations and three resolution settings.
• Includes results from two aerosol flow rates: 0.3 L/min (low-flow) and 1.5 L/min (high-flow).

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's 326.8 KB size suggests a limited scope, likely containing summary or calibration data rather than extensive raw measurements.
