abstract = {In this work we present a detailed technical description of
the system that was set up for long-term on-line
measurements of isoprene and two of its major degradation
products, methyl vinyl ketone and methacrolein in order to
provide a better understanding of the role of forest stands
as a complex source of reactive trace gases into the
troposphere and to elucidate the role of forests as chemical
reactors. Volatile organic compounds (VOCs) are
preconcentrated on cartridges containing a package of two
solid adsorbents (Tenax TA and Carbopack X). Ozone removal
is performed prior to sampling by titration with nitrogen
monoxide. For the calibration and characterization of the
system, a diffusion source was built to produce standard gas
mixtures of up to 16 different compounds with mixing ratios
at tens ppt (parts per trillion) level mixing ratios and
high accuracy. The developed system allows a reliable
quantification of these VOCs (detection limit similar to10
ppt, reproducibility similar $to5\%)$ with a high temporal
resolution (similar to30 min) and has proven to be stable
and run automatically without major maintainence. (C) 2003
