Common procedures are, however, frequently less than satisfactory for organic as well as for mineral samples with very low concentrations of sulfur (<2000 ppm). Here we present a method which employs cold trapping of SO\n 2<\/jats:sub>\n to adjust the gas concentration for subsequent isotope signature determination. Analytical accuracy is comparable with common EA\/CF\u2010IRMS analysis without trapping, showing a precision of better than \u00b10.4\u2030 in\n \u03b4<\/jats:italic>\n 34<\/jats:sup>\n S (1 SD). The virtual absence of memory effects was established by analyzing adjacent samples exhibiting a large difference in\n \u03b4<\/jats:italic>\n 34<\/jats:sup>\n S and by prolonged freezing of the carrier gas, yielding virtually no S concentration peak. The method was tested using less than 15% (6\u2009\u00b5g) of the S required for a conventional isotope analysis at comparable signal intensity. Even smaller samples can be analyzed with high precision. This facilitates the on\u2010line\n \u03b4<\/jats:italic>\n 34<\/jats:sup>\n S determination in small biological and mineral samples, minimizing matrix effects in various materials including sandstone, soil, and plant samples.
