Saharan green corridors and Middle Pleistocene hominin dispersals across the Eastern Desert, Sudan
A New 1MV AMS Facility at Kigam
A 1MV AMS was installed in KIGAM (Korea Institute of Geoscience and Mineral Resources). After 4 months of installation, the AMS started normal operation from January 2008. This multi-element AMS was developed by HVEE to measure 14 C, 10 Be, and 26 Al. The results of an acceptance test demonstrate that this machine is capable of routine 14 C age dating and of measurements of other radioisotopes in terms of accuracy and precision as well as the bac…
Establishment of Chemical Preparation Methods and Development of an Automated Reduction System for AMS Sample Preparation at Kigam
Many previous studies on the sample preparation of various kinds of radiocarbon dating samples by accelerator mass spectrometry (AMS) have been examined at KIGAM (Korea Institute of Geoscience and Mineral Resources) and our own procedures have been established. Furthermore, an automated reduction system has been developed. The volume of the reduction region was minimized to improve the reduction yield, and air-actuated pneumatic valves and soleno…
Simple Pretreatment Method Development for Iron and Calcium Carbonate Samples
Since iron artifacts generally contain trace amounts of carbon, an iron sample needs to be relatively large, as compared to other materials, and a specially designed combustion system is required. An elemental analyzer (EA) was used for the combustion of iron without any special chemical treatment. CO 2 gas with 1 mg of carbon was obtained from the combustion of an iron artifact by using an EA and reduced to graphite for accelerator mass spectrom…
