Measurement of naturally occuring stable isotopes (15N, 13C and 18O) in biological material is a useful tool to investigate questions in ecological research. Measurement of the isotopic composition of a material is made by weighing all individual atoms of a sample to a standard. Isotope ratio mass spectrometry (IRMS) efficiently generates ratios of heavy to light isotopes.
