Abstract

We have recently described an isotopic method for the determination of oxygen1 and carbon2 in organic compounds by using heavy oxygen (O18) and carbon (C13) respectively in conjunction with a mass spectrometer. Using the same method, higher precision is possible in the determination of nitrogen and hydrogen, since N15 and H2 (deuterium) are available in higher concentrations (30–35 per cent for N15) than the oxygen isotope (1.2 per cent) and the carbon isotope (10–20 per cent).
