  • Real-time measurements of chemical compositions of secondary organic aerosol and analysis of reaction mechanisms using Single Aerosol Laser Mass Spectrometer

    A home-made Single Aerosol Laser Mass Spectrometer (SALMS) was utilised to provide on-line measurements of the sizes and molecular compositions of Secondary Organic Aerosols (SOAs) from irradiating toluene in the smog chamber. Results demonstrate that variations in reaction conditions make a little difference in the size and chemical composition distributions of SOAs. According to the reaction ...

  • Experimental evaluation of Aerosol concentrators

    Introduction An aerosol concentrator is a vital component of any front-end sampling module used to introduce aerosol particles to a chemical or biological identification sensor (Hart et al, 2000). Because these sensors need to have a minimum amount of sample to make a positive identification, particle concentration is often necessary, making it critical to know the concentration factor of ...

  • European On-Line Particle Mass Spectrometry

    An international workshop on European On-line Particle Mass Spectrometry (PMS) was held 29th-30th of November 2005 at the JRC in Ispra, Italy. The main goals of the Workshop were: 1) To get together all European scientists involved in the field of PMS 2) To review the latest scientific progress on the field of PMS, with particular emphasis on:a. New instrumentationsb. Data analysisc. ...


  • A high-performance aerosol concentrator for biological agent detection

    Introduction Particle sampling from ambient air is a well-developed technology described in many texts (e.g., Vincent 1989; Willeke and Baron 1993; Hinds 1999). However, there are many cases in which the concentration of airborne particles is so low that it becomes necessary to sample for extended periods of time to collect enough mass for chemical or biological characterization of the ...

  • Air Monitoring for the Gulf Oil Spill

    Ambient air monitoring is a priority in the ongoing efforts to contain and manage the oil spill from the Deepwater Horizon in the Gulf of Mexico. The following provides information about the kinds of airborne contaminants that are currently being monitored in the Gulf, how they are collected and how they are analyzed. For a given project, a suitable sampling plan – developed by ...
