A novel procedure for measuring the concentration of sulfur in different inorganic and biological samples has been studied using /sup 18/O heavy ion activation analysis. The specific reaction, /sup 32/S(/sup 18/O,t)/sup 47/V, is sensitive and completely selective if the bombardment energy is 39 MeV /sup 18/O/sup 6 +/. The detection limit for nondestructive analysis is 0.6 ng for a 2 h irradiation in 100-nA beam current. A precision of +/-27% was achieved at the 20 ..mu..g.g/sup -1/ level. Sulfur has been determined nondestructively and destructively in two standard metals, IRSID 508-1 and NBS-SRM 394. Steel, ceramic, and biological specimens were also analyzed. This method can be applied nondestructively without any interference to almost any type of solid samples.
