Has anybody here had any experience with trying to analyse d34S of native sulfur by elemental analysis-continuous flow isotope analysis? Someone has asked me about the possibility of running these analyses. I seem to recall that native S doesn't combust very easily, so I'm a bit concerned about the possibility that I'd get incomplete combustion and that the S would vaporize and then condense into the pipework further along the system.
