| Abstract | An on-line method for S-isotope analysis is described. Samples are combusted in an elemental analyzer. SO 2 is separated from other combustion gases by gas chromatography, and the gases enter the ion source of the mass spectrometer through a split interface. Integrated peak areas for 32 SO 2 + and 34 O 2 + are compared to the response for a standard gas sample to determine the δ 34 S value. δ 34 S values of samples analyzed using the on-line method correspond linearly with those achieved from the same sample prepared off-line, where Kiba reduction followed by oxidation of the sulfur to SO 2 is carried out prior to S-isotope analysis against a known standard. With the described on-line method, the amount of sulfur necessary for S-isotope analysis is reduced to about 10 μg of S per analysis |
