For Accelerator Mass Spectrometry 1 mg is needed. AMS samples are prepared at the WIS and are sent to the AMS 14C radiocarbon lab ADD LINK at Aarhus University for the 14C determination. Longer counting time or multiple 14C determination may increase the precision. A close collaboration with the submitter is therefore important for a correct sample preparation and measurement. The radiocarbon laboratory at the Weizmann Institute is equipped for the measurement of Tritium.
Enrichment is used for high precision.
Samples of about 0.5 liter are needed for enrichment.
