Setup for real-time automotive exhaust monitoring with PTR-TOF

IONICON PTR-MS is known for being an analytical technique to quantify hydrocarbons and VOCs with high sensitivity and in real-time. The capability to monitor emissions in real-time is particularly useful for recording the fast changing conditions in the combustion process and to assess the impact of control technologies.

Especially the initial cold start phase in cars, which is responsible for a large fraction of emitted compounds, as well as hard acceleration phases, require a real-time analysis. Looking at the exhaust composition allows investigating which processes and parameters are responsible for those emissions.
Major reasons our customers choose PTR-TOFMS to monitor exhaust emissions:

  • Emission rates change rapidly with engine operating conditions, thus a high time resolution measurement is important.
  • In contrast to offline methods, real-time analysis allows the measurement of critical compounds. For example, acrolein is an unstable compound which may easily get lost in offline sampling procedure.
  • High sensitivity and good separation of isobaric compounds.
