First, I would like to apologize for posting this request on this
listserv. Normally I would look up the answer in the library, but I
am in Barbados for a month and access to scientific literature.
I do my work on a Europa Single Inlet Mass Spec and obtains good result
for N-15 ratios for animal tissues. I would like to isolate enough
nitrate from ground waters here on the island to test for some
human waste origin (which can be as high as 20 o/oo). My question is:
How can this be done. Does anbody know of a recipe? I figure that
I need about 50 mg N for it to work on the Europa.
Thank you for your time,
