Comprehensive nanoparticle monitoring solutions

Nanoparticles significantly affect climate, health, and industrial efficiency. In the environment, they influence phenomena like cloud formation and radiative forcing, contributing to climate change. In public health, their ability to penetrate deep into the lungs and bloodstream makes them a pressing concern for respiratory and cardiovascular health. For industries, nanoparticle behavior affects product quality and process efficiency, especially in combustion systems and material synthesis.

Fundamental nanoparticle research in laboratories has unlocked a deeper understanding of particle nucleation, growth dynamics, and chemical interactions. This knowledge is essential for developing solutions to environmental challenges, advancing nanotechnology applications, and informing regulatory policies.

Airborne particulate matter (PM), such as PM2.5 and PM10, is typically regulated using mass-based limits, but focusing solely on mass overlooks critical health risks. Smaller particles, particularly ultrafine particles (UFPs) with diameters below 0.1 µm, contribute very little to total particle mass but are the most numerous. Despite their minimal mass, UFPs can penetrate deeply into the lungs, reaching the alveoli, and even enter the bloodstream, where they pose significant health risks. Research suggests that particle number concentration (PNC) correlates more strongly with adverse health effects, such as cardiovascular disease, respiratory conditions, and neurological disorders, than particle mass.

One reason for this is the high surface area of UFPs, which allows them to carry toxic chemicals into the body, amplifying their harmful effects despite their negligible contribution to mass. Current mass-based regulations, such as PM10 and PM2.5 limits, fail to account for the unique health risks of UFPs, potentially underestimating harmful exposures in urban and industrial environments. Measuring particle number offers a more detailed understanding of air quality, particularly in areas dominated by combustion sources like traffic, which emit large quantities of UFPs. Incorporating particle number limits into air quality standards would close this gap, better protecting public health from these often-overlooked dangers.

GRIMM AEROSOL TECHNIK is at the forefront of solutions for nanoparticle monitoring in ambient air, particularly in response to the new EU Ambient Air Quality Directive. This directive mandates the monitoring of ultrafine particles in ambient air networks, reflecting growing awareness of their environmental and health impacts. GRIMM offers a comprehensive portfolio of CEN-compliant instruments, including:

• CEN-SMPS+C: Combines DMA with CPC technology to deliver high-resolution size distribution data.
• CEN-CPC: Dedicated ultrafine particle counters for accurate, real-time concentration measurements.

These systems are designed to seamlessly integrate into monitoring networks, helping organizations meet regulatory requirements while advancing air quality management efforts.

Our nanoparticle measurement solutions address a wide array of applications:

• Public health and environmental monitoring: Supporting epidemiological studies and air quality assessments.
• Industrial emission control: Ensuring compliance with emission standards, such as Euro 5 and 6, and optimizing industrial processes.
• Fundamental laboratory research: Advancing the understanding of nanoparticle behavior, including nucleation, growth dynamics, and chemical interactions, to drive innovation in nanotechnology and environmental science.
