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.","subitem_description_type":"Abstract"}]},"item_25_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.14945/00000381","subitem_identifier_reg_type":"JaLC"}]},"item_25_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"静岡大学地球科学教室"}]},"item_25_relation_22":{"attribute_name":"NII論文ID","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"110000413420","subitem_relation_type_select":"NAID"}}]},"item_25_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03886298","subitem_source_identifier_type":"ISSN"}]},"item_25_source_id_23":{"attribute_name":"NII書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00103190","subitem_source_identifier_type":"NCID"}]},"item_25_subject_8":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"452","subitem_subject_scheme":"NDC"}]},"item_25_version_type_32":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"土屋, 理恵"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"和田, 秀樹"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-12-14"}],"displaytype":"detail","filename":"KJ00000102496.pdf","filesize":[{"value":"658.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000102496.pdf","url":"https://shizuoka.repo.nii.ac.jp/record/461/files/KJ00000102496.pdf"},"version_id":"1b295b2f-1493-40f8-a21a-135d816043e4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"〓CO_2 extraction","subitem_subject_scheme":"Other"},{"subitem_subject":"vacuum system","subitem_subject_scheme":"Other"},{"subitem_subject":"^<l4>C","subitem_subject_scheme":"Other"},{"subitem_subject":"seawater","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"加速器質量分析計による^<14>C測定のための海水溶存無機炭素真空抽出法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"加速器質量分析計による^<14>C測定のための海水溶存無機炭素真空抽出法"}]},"item_type_id":"25","owner":"3","path":["116"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-25"},"publish_date":"2008-01-25","publish_status":"0","recid":"461","relation_version_is_last":true,"title":["加速器質量分析計による^<14>C測定のための海水溶存無機炭素真空抽出法"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2024-02-19T05:38:30.940458+00:00"}
