Dear colleagues,

Just recently I signed up to your network; I skimmed the archives and its
very interesting and stimulating to see all the expertise present here. I
hope I can build on that concerning the following issue: We would like to do
some 129Xe NMR experiments on a high resolution 400 MHz spectrometer to
determine, in polymer material, the volume fraction of the different phases
present. Since some of the volume fractions are anticipated to be rather
small, the experiments has to be carried out at high pressure or, in order
to increase the sensitivity even further, laser polarised 129Xe has to be
used. So my question is: -Who has experience with 129Xe NMR in general and
with laser polarised 129Xe specifically?- I would like to do some trials
somewhere in order to find out what kind of kit we should buy to do the
experiments in-house.

Many thanks in advance,

Dr. Rene Klein
