Accelerator mass spectrometry dating
It is ionised by bombarding it with caesium ions and then focused into fast-moving beam (energy typically 25ke V).The ions produced are negative which prevents the confusion of ions). As they travel to the terminal (which is at about 2MV), they are accelerated so much that when they collide with the gas molecules in the central `stripper canal'.The mass of these ions is then measured by the application of magnetic and electric fields.
These ratios provide useful information on the purity of the sample and clues about the diet and climatic conditions of the living organism.
Hosted by the Institute of Physics - Centre for Science and Education, Silesian University of Technology, will be held in Gliwice, Poland.
3rd International Radiocarbon in the Environment Conference.
As an example bones are treated as follows: Several of these procedures are done in an automated continuous flow system.
After chemical pre-treatment, the samples are burnt to produce carbon dioxide and nitrogen.
Accelerator mass spectrometry (AMS) is a technique for measuring long-lived radionuclides that occur naturally in our environment.
