Dear list members,

I wish to contact someone who is actively running micro-diffusions for
the N-15 analysis of ammonium ion.  I have about 30 hot spring water
samples to analyze (conc up to 50 ppm; HACH kit) and I would rather have
a skilled researcher run these than try to develop the technique
myself.

If anyone is interested or knows of a potential contact, please e-mail
me offline at [log in to unmask]

Thanks in advance,
