Long and short term changes in climate can have a dramatic impact on the ways in which people may procure or produce their food.

Isotope Analysis Methods In order to investigate stable isotopes from human and animal bones, a very small sample of bone is needed for the analysis.

Due to advances in accelerated mass spectrometry (AMS) a small sample which can range from 200 milligrams to 1gram of bone can be used.

The mass spectrometer works by measuring the masses and relative concentrations of atoms and molecules.

These are compared using standard reference materials that are set by the International Atomic Energy Agency in Vienna.

The small bone sample is then treated through a set of chemical procedures, depending on the particular analysis in question.
