Summary:In a method and apparatus for detecting compounds in a gas stream, the gas stream with the compounds to be detected is conducted into an ionization chamber of a mass spectrometer where the gas stream is subjected in the ion chamber in a pulsed manner alternately to UV laser pulses and to vacuum ultraviolet VUV laser pulses and the ions generated thereby are directed into the mass spectrometer for detection therein to determine the compounds in the gas stream.
