Whereas the hyphenation of gas chromatography (GC)
with mass spectrometry is of great importance, little is
known about the coupling to nuclear magnetic resonance
spectroscopy (NMR). The investigation of this technique
is an attractive proposition because of the valuable
information given by NMR on molecular structure. The
experiments shown here are to our knowledge the first
hyphenating capillary GC to microcoil NMR. In contrast
to liquids, gases have rarely been investigated by NMR,
mainly due to the experimental difficulties in handling
gases and the low signal-to-noise-ratio (SNR) of the NMR
