Our team was proud to participate in the 43rd Annual Conference of the American Association for Aerosol Research (AAAR 2025). The event brought together leading scientists, engineers, and industry professionals to share the latest advancements in aerosol science and technology.

Overview

Our integrated technologies provide a uniquely comprehensive approach to advancing aerosol research. The Bipolar FUSION PTR-TOF offers unprecedented molecular characterization of complex oxidation pathways and SOA formation using switchable reagent ions. When coupled with the CHARON particle inlet, it provides real-time, molecular analysis of both volatile and condensed organics. Complementing this, the IONICON Laminar-Flow Oxidation Reactor ILOx allows for dynamic simulation of multi-day atmospheric aging, while the VOCentinel ensures automated, continuous monitoring of critical VOC precursors, securing high-quality, long-term environmental data.

Highlights from our contributions

Our team presented several talks and posters across multiple sessions, sharing recent developments in instrumentation and atmospheric chemistry research:

  • VOCentinel – A Novel Solution for Automated Real-Time Monitoring of Atmospheric VOCs
  • Characterization of a Novel Laminar-Flow Oxidation Reactor for Simulating Atmospheric Multiple-Day Oxidation: CHARON & ILOx
  • Bipolar FUSION PTR-TOF Mass Spectrometer: Advantages of Multiple Reagent Ions to Characterize Oxidation and Secondary Organic Aerosol Formation
  • PTR-TOF: Real-Time Analysis of Volatile and Condensed Organics on a Molecular Composition Level

  • Insights on the Importance of Intermediate and Semi-Volatile Organic Precursor Compounds in the Formation of Ambient Secondary Organic Aerosols (SOA): ILOx
