Don’t Be Fooled by Mass: Why Counting Particles Is One Way Street for Sub-micron Air Quality Monitoring
While monitoring air quality, scientists traditionally relied on mass concentration to measure particulate matter (PM). This metric tells you the total mass of particles per unit volume of air. But for sub-micron particles – those less …
While monitoring air quality, scientists traditionally relied on mass concentration to measure particulate matter (PM). This metric tells you the total mass of particles per unit volume of air. But for sub-micron particles – those less than one micrometer in diameter – mass concentration falls short. Here's why measuring particle number by size distribution is a superior approach. The […]
