Presentation Overview

Photochemical Assessment Monitoring Stations (PAMS) are used in the monitoring of volatile organic compounds, including ozone precursors. These are compounds of interest in urban environments around the world as their presence is believed to contribute to the formation of ground-level ozone and urban smog.
In this webinar, Pete Furdyna from the New York State Department of Environmental Conservation (NYSDEC) gives us a walk-through of its automated PAMS monitoring system located at the New York Botanic Gardens in the Bronx in New York City, and explains how they have achieved and regularly maintain exceptional data quality. Pete also provides some insights into the effects that limited automotive traffic in New York City during COVID-19 lockdowns had on PAMS data.

His presentation focuses on monitoring of ozone precursors in accordance with the US EPA PAMS program. He shares his experiences on PAMS monitoring including challenges encountered, how they were overcome with Markes’ on-line systems, and useful tips and considerations for maintaining optimum system performance.

By viewing this presentation you will learn:

  • How NYSDEC achieved excellent data stability over extended sampling periods.
  • How water can be effectively managed for sample integrity and to achieve sub-ppb levels of detection for ozone precursor VOCs.
  • Benefits of using hydrogen carrier gas for continuous, robust and unattended monitoring in remote locations.
Why should you view it?

  • Multi-gas enabled thermal desorption instruments provide you with the ability to operate your TD-GCMS analysis using hydrogen carrier gas; this is a more sustainable gas option that is ideal for use in remote locations and wherever using cylinders is difficult
  • See how this technology is being used by analysts like you, to address some of the challenges faced in environmental monitoring.

Who should view it?
• Environmental scientists
• Laboratory Managers / Directors / Supervisors
• Researchers into ozone precursors and VOCs
