Join TOFWERK at ASMS 2018!

The 66th ASMS Conference on Mass Spectrometry and Allied Topics will be in San Diego, CA  from June 3-7, 2018. With over 6,500 scientists attending and 3,000 papers presented as posters and/or talks, ASMS 2018 will provide an exciting look into the latest research and developments in mass spectrometry. 

At ASMS 2018, our Vocus PTR-TOF R&D scientist, Felipe Lopez will present an overview of the Vocus proton transfer reaction cell and highlight recent applications, including mobile measurements of trace VOCs near natural gas operations.  

Monday, June 4
MP 379, 10:30 – 11:30 am & 12:30 – 2:30 pm
Ultra sensitive (ppqv) online VOC detection utilizing an ion molecule reactor with both RF and DC fields: Application to Proton Transfer Reaction Time of Flight Mass Spectrometry
Felipe Lopez, TOFWERK, Switzerland

  • Chemical Ionization Mass Spectrometry is a sensitive and selective method for VOC detection without the need for sample prep or pre-separation (e.g. GC).
  • We present a novel reactor which results in 10x better sensitivity than previous state of the art instruments, achieving sub pptv detection limits in seconds.
  • The Vocus reactor is coupled to a time of flight mass spectrometer with resolution up to 15,000
  •  The Vocus reactor, with its improved sensitivity supports new applications where ultra low detection limits, and/or high speed measurements of VOC are required
