abstract = {This paper presents results from the first large-scale in
situ intercomparison of oxygenated volatile organic compound
(OVOC) measurements. The intercomparison was conducted blind
at the large (270 m(3)) simulation chamber, Simulation of
Atmospheric Photochemistry in a Large Reaction Chamber
(SAPHIR), in Julich, Germany. Fifteen analytical
instruments, representing a wide range of techniques, were
challenged with measuring atmospherically relevant OVOC
species and toluene (14 species, C-1 to C-7) in the
approximate range of 0.5-10 ppbv under three different
conditions: (1) OVOCs with no humidity or ozone, (2) OVOCs
with humidity added (r.h. approximate to $50\%),$ and (3)
OVOCs with ozone (approximate to 60 ppbv) and humidity (r.h.
approximate to $50\%).$ The SAPHIR chamber proved to be an
excellent facility for conducting this experiment.
Measurements from individual instruments were compared to
mixing ratios calculated from the chamber volume and the
known amount of OVOC injected into the chamber. Benzaldehyde
and 1-butanol, compounds with the lowest vapor pressure of
those studied, presented the most overall difficulty because
of a less than quantitative transfer through some of the
participants' analytical systems. The performance of each
individual instrument is evaluated with respect to reference
values in terms of time series and correlation plots for
each compound under the three measurement conditions. A few
of the instruments performed very well, closely matching the
reference values, and all techniques demonstrated the
potential for quantitative OVOC measurements. However, this
study showed that nonzero offsets are present for specific
compounds in a number of instruments and overall
improvements are necessary for the majority of the
techniques evaluated here.},
