✦ Synopsis

Sulfur is recovered as silver sulfide which is converted to sulfur dioxide by combustion with pure oxygen at low pressure in 1 min. Isotopic analysis of as little as 40 ccg of sulfur is possible with a precision better than 0.2%. The technique is applicable to materials such as Cu, Fe, Sn, Ti, Zr, zircaloys and standard rocks.
