Application Brief

Analysis of Airborne Particles on Air Filters Using ICP-OES

Accurate monitoring of airborne particulate matter is essential for assessing environmental and occupational health risks, particularly when it comes to toxic heavy metals such as lead, arsenic, and cadmium. This application report presents a validated method for the elemental analysis of air filters using inductively coupled plasma optical emission spectrometry (ICP-OES). This approach supports compliance with the methods for the determination of inorganic compounds in air, including EPA IO-3.4 and EN 14385, and is suitable for routine use in environmental laboratories and agencies.

The study demonstrates how air filters can be digested and analyzed to quantify trace elements with high accuracy and precision. Certified reference material was used to validate the method, showing recovery rates between 98% and 110% across 17 elements. The use of axial plasma observation and optimized calibration protocols ensures reliable detection limits in the low µg/L range. This makes the method ideal for identifying and quantifying airborne contaminants from industrial emissions and combustion processes.

Powered by the SPECTROGREEN ICP-OES system, the method benefits from dual plasma observation and high-resolution optics, enabling simultaneous analysis of major and trace elements in a single run. The system’s robust design and software-controlled parameters contribute to consistent performance in high-throughput environments.

Key Benefits:
- Complies with international air quality monitoring standards
- Enables precise trace metal detection in airborne particulate matter
- Validated with certified reference material for reliable accuracy
