Resonance-enhanced multiphoton ionization-time-of-flight mass spectrometry
(REMPI TOFMS) is a selective as well as sensitive analytical technique, wel
l suited for real-time on-line monitoring of organic compounds in complex p
yrolysis gases. In the present work, the on-line REMPI-TOFMS technique was
applied to investigate dynamic effects in 'all day' pyrolytic processes, na
mely the coffee roasting process and tobacco smoking. (C) 1999 Elsevier Sci
