Compound-Specific 34 S Analysis of Volatile

We have developed a highly sensitive and robust method
for the analysis of 34
S in individual organic compounds
by coupled gas chromatography (GC) and multicollec-
tor inductively coupled plasma mass spectrometry
(MC-ICPMS). The system requires minimal alteration
of commercial hardware and is amenable to virtually
all sample introduction methods. Isobaric interference
from O2
+
is minimized by employing dry plasma
conditions and is cleanly resolved at all masses using
medium resolution on the Thermo Neptune MC-
ICPMS. Correction for mass bias is accomplished
