An improved, automated whole air sampler and gas chromatography mass spectrometry analysis system for volatile organic compounds in the atmosphere
Volatile organic compounds were quantified during two aircraft-based field campaigns using highly automated, whole air samplers with expedited post-flight analysis via a new custom-built, field-deployable gas chromatography–mass spectrometry instrument. During flight, air samples were pressurized wi...

description |
Volatile organic compounds were quantified during two aircraft-based field
campaigns using highly automated, whole air samplers with expedited
post-flight analysis via a new custom-built, field-deployable gas
chromatography–mass spectrometry instrument. During flight, air samples
were pressurized with a stainless steel bellows compressor into
electropolished stainless steel canisters. The air samples were analyzed
using a novel gas chromatograph system designed specifically for field use
which eliminates the need for liquid nitrogen. Instead, a Stirling cooler is
used for cryogenic sample pre-concentration at temperatures as low as
−165 °C. The analysis system was fully automated on a 20 min
cycle to allow for unattended processing of an entire flight of 72 sample
canisters within 30 h, thereby reducing typical sample residence times
in the canisters to less than 3 days. The new analytical system is
capable of quantifying a wide suite of C2 to C10 organic compounds at
part-per-trillion sensitivity. This paper describes the sampling and
analysis systems, along with the data analysis procedures which include a
new peak-fitting software package for rapid chromatographic data reduction.
Instrument sensitivities, uncertainties and system artifacts are presented
for 35 trace gas species in canister samples. Comparisons of reported mixing
ratios from each field campaign with measurements from other instruments are
also presented. |
