What is the main purpose of using sorbent tubes in air sampling?

The primary purpose of using sorbent tubes in air sampling is to sample hazardous vapors. Sorbent tubes contain materials that can adsorb specific gases and vapors present in the air, allowing for the collection of airborne contaminants for subsequent analysis. This method is particularly effective for identifying and quantifying volatile organic compounds (VOCs), solvents, and other hazardous substances that may pose health risks in occupational settings.

Sorbent tubes can capture vapors as air is drawn through them, making it possible to collect a representative sample over time. Once collected, the sorbent material can be analyzed in a laboratory to determine the concentrations of harmful chemicals, aiding in risk assessment and ensuring a safe working environment.

While other methods can assess dust particles, humidity, or temperature, they do not employ sorbent tubes. The function of sorbent tubes is specifically aligned with the need to monitor and evaluate exposure to harmful vapors, ensuring the focus on air quality and worker safety.
