This paper presents a method of measuring on line ppbv level of BTX and PAH tar for biomass gasification applications. This method is based on the Ion Molecule Reaction (IMR) mass spectrometer principle. Due to the low energy of ionisation of Hg, Xe or Kr almost no overlapping spectra can damage the interpretation of the detected results. IMR-MS results of concentrated and trace tars are presented after a bubbling fluidized bed and a tar cracker...
