Overcoming challenges for air analysis of hazardous air pollutants (HAPs)
On-demand webinar
Event Overview
Environmental laboratories face significant challenges for air analysis of hazardous air pollutants (HAPs), which includes the ability to see a wide range of analytes while achieving a high sample throughput. High moisture content of environmental air samples also causes a problem for analysts. Moisture must be eliminated to safeguard the quality of data and instrument uptime.
HAPs are volatile organic compounds (VOCs) ranging in volatility from propene to naphthalene and include polar and chlorinated compounds such as methylene chloride (dichloromethane) as well as non-polar compounds. They are monitored in many industrial and urban environments as a measure of air quality, and are regulated under international standard methods, including US EPA methods TO-17 and 325B.
In this webinar, environmental expert Maya Murshak demonstrates how Merit Laboratories uses automated thermal desorption (TD) technology to overcome these challenges and enhance their analysis of volatile organic air toxics and HAPs, while extending their analysis for semi-volatile organic compounds (SVOCs) such as polyaromatic hydrocarbons (PAHs) and per-and polyfluoroalkyl substances (PFAS).
By watching this presentation, you will learn:
- Best practices for standard methods for monitoring air toxics in air using TD-GC-MS such as US EPA methods TO-17 and 325B for fenceline monitoring
- How to effectively manage water in your samples
- How contract labs employ TD–GC–MS technologies to automate and improve their air monitoring workflow, remove moisture, and increase throughput for a wide range of analytes
