Breathing is a prerequisite for life. We all need clean and breathable air to survive, which can be hard to find in an industrial and urban environment full of dust, smoke and gases. Poor air quality can lead to respiratory diseases, cardiovascular problems, and environmental damage. As a result, the monitoring of air quality has become an important issue in recent years.
Sampling ambient air involves collecting a representative sample of ambient air for the analysis of contaminants. It is done indoors e.g. to guarantee safe work environment or outdoor close to major transportation routes, industrial or agricultural areas. There are two general approaches: “whole air” sampling with Canisters or Tedlar bags or “in-field concentration” sampling using sorbent tubes or cold traps. Here we focus on ‘whole air’ sampling with canisters.
Air sampling with canisters is a method used to collect and analyse air for various contaminants, including volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and other trace gases. Canisters, typically made of stainless steel, are airtight containers that can hold a vacuum or pressurised air sample, allowing for the collection of ambient air in a controlled manner. However, proper calibration, handling, and analysis are crucial to ensure the accuracy and reliability of the results.
In Restek’s comprehensive guide to ‘Whole Air Canister Sampling’ you’ll find an introduction to system components, as well as a process for assembling and preparing your system. Plus, check out the invaluable tips and tricks for advice on collecting reliable and reproducible data, proper evaluation, cleaning procedures and how to enhance the lifetime of your canisters.
