内容記述 | We have established a method for total inorganic carbon(〓CO_2) extraction from seawater using a vacuum system for radiocarbon content analysis using an Accelerator Mass Spectrometry (AMS). In this method, phosphoric acid is added to the seawater sample and 〓CO_2 is extracted with ultrasonic washer. After this operation, the extracted gas is purified cryogenically to CO_2 using Horibe traps set with n-pentane (-130℃) and liquid nitrogen (-196℃) to remove H_2O. The collected CO_2 is reacted with H_2 and converted to graphite. The yield of CO_2 extracted from seawater is about 99.8%. The radiocarbon isotopic accuracy of this method is espected to be better than ±0.04‰ in Δ ^<l4>C. Stable carbon isotopic composition (δ^<l3>C) of residual 〓CO_2 in the sample is almost identical with that of initial extraction. | |||||||
