research. The use of stable isotopes is not complicated by health hazards, dangers of
radiation or time limit for experiments as is the case for radioactive isotopes. However,
the analytical methods available for the determination of stable isotopes are much less
sensitive, considerably more complicated and time consuming than those for radioactive
isotopes. Such methods usually require the use of a mass spectrometer and most employ
the combustion technique (Dumas method) for sample presentation. Speciation can be
achieved by an isotope ratio mass spectrometer coupled to a gas chromatograph (GC) and
combustion interface. Such instruments are expensive and labour intensive. Additionally,
the consumables and catalysts employed are costly. [Continues.]
