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, z

A simple, rapid and sensitive method for procaine determination is described. Isotope dilution mass spectrometry with ("N)procaine as internal standard was used. The analysis was performed at 4OOO resolution by selected ion monitoring with temperature programming. The sample was measured in underiva
