Gary, Sulfur is a pig. Well now that I've got that off my chest.
We can help you. We have done hundreds of fish tissue, animal samples.
This is not fun. The water content even as h and O in the molecules of the samples
screws up the system and often standards and repeats are all over the place. The
problem is that 18O looks like 34S to the mass spec. and if anything alters the 18O
like water moving through the system. The drier the sample is the better the runs.
We need about 10mg of freeze dried, ground tissue. The cost is $33.15US.
Results should be available within 8 weeks unless we have problems.
