摘要：

CN analyzer was already applied in CO2 preparation system for AMS dating in the Research Lab for Archaeology & the History of Art in Oxford several years ago [1]. Now a line of combustion with an Elementar Vario EL CHNS elemental analyzer was built in the Dating Lab in the Department of Archaeology at Peking University. This system has many advantages, such as obtaining purer CO2 simultaneously measuring C, N, S etc. elements and C/N. A sample gases (i.e., CO2, CO etc.) recollection system was also built in this lab to recover the CO2 in case of the failure of graphitization. (C) 2000 Elsevier Science B.V. All rights reserved.
