Subject: Sulfur analysis


Dear List members:

                I am looking for 3 reputable labs with good QA/QC
procedures who routinely analyze for sulfur
((superscript: 34)S/(superscript: 32)S) in organic samples. I have
investigated two such labs (Univ. of Waterloo & Univ. of Calgary), but need
1 more before making a decision. Any thoughts or suggestions from those who
have had organic samples analyzed for sulfur would be appreciated.

                                   Thanks-
                                   Bryan Taplin
