Stable isotopes have been successfully used as tracers in the most varied fields of pure Science and technology. The freedom from radiation Problems makes the preparation and handling of such isotopes and Compounds labelled with them attractive in many tracer applications where the use of even very small amounts of radioactivity is not considered acceptable (e.g. diagnostic studies in pregnant women and children). This, together with the fact that for some elements of interest (e.g. nitrogen and oxygen) there is no suitable radioisotope of sufficiently long half-life for tracer applications, has led to the expanding use of separated Stahle isotopes in organic Chemistry, biochemistry, pharmacology and in the life Sciences generally. Moreover, in certain cases, more information can be obtained by the use of a stable isotope than by the use of a corresponding radioisotope. The decreasing cost and increasing availability of separated stable isotopes, especially of carbon, oxygen, nitrogen and sulphur, together with new developments in instrumentation and techniques for sample Processing and measurement, assure their applications on an increasing scale in studies of both living and non-living Systems. ...
