 note = {This paper shows a method for dissolved inorganic carbon (DIC) extraction from seawater using a vacuum system for radiocarbon content analysis using an accelerator mass spectrometry. In this method, phosphoric acid is added to the seawater sample, and DIC is extracted with ultrasonic bath. After this operation, the extracted gases are purified to CO2 gas using n-pentane slush (-130℃) and liquid nitrogen trap(-196℃). The yield of CO2 gas extracted from seawater is more than 99%., 名古屋大学年代測定総合研究センターシンポジウム報告},
