There is an increasing demand for accurate and efficient air quality monitoring, driven by growing public awareness and stricter regulations. Laboratories and environmental agencies face the challenge of detecting hazardous air pollutants and volatile organic compounds (VOCs) with both precision and efficiency. Achieving compliance with monitoring methodologies—such as US EPA Methods TO-15A and TO-17 and Chinese EPA Method HJ 759—requires advanced technologies that provide highly sensitive trace VOC detection while remaining user-friendly, flexible, and easy to operate.
This eBook presents gold-standard technologies for air monitoring, including tube, canister, or online sampling, with a focus on the latest thermal desorption (TD) and automated pre-concentration techniques for GC-MS. These methods not only ensure compliance with global air monitoring regulations but also offer exceptional precision and sensitivity. Moreover, they eliminate the need for solvents and cryogenic cooling, providing cost-saving benefits and improved performance in environments with high humidity and complex pollutant profiles.
The eBook offers detailed insights into how cutting-edge air monitoring technologies are setting new standards for regulatory compliance and VOC detection in complex air samples.
