Gas detection

  1. I am looking for a way to map gases over a city, what are some ways I could do that? This is a theoretical experiment so cost is not an issue. Thanks in advance

    Use a gas detector and a GPS.
  4. What sort ppm can I get something like that? And also how does said gas detector work?
  5. I am not sure bt i think you can use gas detector with ppm reading you can also using remote sensing and gps system.

    People do this already. A mass spectrometer with an air sampler (essentially a small leak of air into the spectrometer) combined with GPS. Some optical measurements will work with gases with strong absorbances, but mass spec. is probably the most universal.
