摘要：

The new line for preparation of graphite samples for C-14 dating by AMS has been constructed in the Zagreb Radiocarbon Laboratory. The performance of the rig and sample preparation procedure has been validated by preparing graphites from various reference materials of known C-14 activity. The yield of the graphitization was good and the measured fraction of modern carbon (F-m) values have not significantly deviated from the expected ones. Detailed analysis of measured F-m values indicates a slight bias to more positive values and should be carefully investigated. (C) 2009 Elsevier B.V. All rights reserved.
