Sulfur can be determined by ICP-AE. There are several wavelengths in the
180-182nm range. One of them has a BIG Ca interence i just cant recall
which one at this moment.
If this is a radial IRIS, you should be able to do low ppms pretty easily.
be careful of the digestion method. sulfur speciation could be an issue
with mass transport if the S compound is significantly different from your
Aq. S std mix.

Subject: Sulfur analysis
Dear list members,
We would like to analyze sulfur content in our protein and are wondering
what would be the best method to do it with. We have a Thermo Iris 1000
which is mostly utilized for heavy metal analysis. Is it possible to look
at sulfur using ICP-AE and which concentrations should we aim at. Could
ICP-MS be utilized?
