By attending this presentation, you will learn:
- The changes necessary for achieving TO-15A defensible data
Method TO-15A, for the monitoring of air toxics, was released in 2020 and lowers the required method detection limit for all compounds covered by the method to 20 ppt. This new, lower detection limit level challenges every aspect of the sampling and analysis process, especially blank levels. Background generated by instrumentation and sampling equipment has always been monitored for air toxic analysis, but these extremely low detection limits enhance the associated demands on the analyst.
In this webinar, we will show how the use of the UNITY-CIA Advantage-xr, a canister autosampler and pre-concentrator, combined with Kori-xr for innovative water removal enables a robust analysis at a range of humidities, in accordance with US EPA Method TO-15A. Within this, we will demonstrate how the analytical instrument overcomes the challenges related to the low detection limits and background and discuss the obstacles involved in extending this method to new species of concern such as ethylene oxide.
Who should attend?
- Researchers interested in monitoring of volatile organic compounds in air
- Laboratory and project managers specializing in air samples and air monitoring
- GC-MS scientists, analysts, and lab technicians
- Environmental consultants
