Abstract:Elemental analysis
(EA) coupled to isotope ratio mass
spectrometry
(IRMS) is a well-established method to derive stable isotope ratios
of sulfur (34S/32S). Conversion of sulfur to
SO2 by EA and measurement of SO2 isotopologues
by IRMS represents the simplest and most versatile method to accomplish
isotope measurement of sulfur even in bulk samples. Yet, interferences
by oxygen isotopes in SO2 often impair the precision and
trueness of measured results. In the current study, we coupled EA
to multicollector indu… Show more
