The concentration of methane in the atmosphere is too low to measure its carbon isotopic ratios without enrichment. We assemble a preparation line for the analyses of these ratios. This line enriches methane in air sample more than 1m^3 by adsorption under low temperature, and separates it from the other gas components with gas chromatography. The enriched methane is finally turned to carbon dioxide through the combustion tube in this line. The efficiency of methane collection with this line is examined using air sample and standard methane diluted with nitrogen, and it is more than 80% for the former sample and more than 90% for the latter one. The carbon isotopic ratios (^<14>C/^<13>C) in the latter two samples are 0.00512±0.00091 and 0.01184±0.00072. These ratios are almost the background level (0.00587±0.00004), and that shows the contamination with the atmospheric air of high ^<14>C/^<13>C ratio in this line is little and negligible.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"タンデトロン加速器質量分析計業境報告 Summaries of Researches Using AMS","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18999/sumrua.4.77","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"名古屋大学年代測定資料研究センター 天然放射性元素測定小委員会","subitem_publisher_language":"ja"}]},"item_9_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110000475832/","subitem_relation_type_select":"URI"}}]},"item_9_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"名古屋大学年代測定資料研究センター 天然放射性元素測定小委員会","subitem_rights_language":"ja"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである","subitem_rights_language":"ja"}]},"item_9_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_9_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森泉, 純","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"79746","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Moriizumi, Jun","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"79747","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"永峰, 康一郎","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"79748","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nagamine, Koichiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"79749","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"飯田, 孝夫","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"79750","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iida, Takao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"79751","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-20"}],"displaytype":"detail","filename":"KJ00000187573.pdf","filesize":[{"value":"344.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000187573.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/11349/files/KJ00000187573.pdf"},"version_id":"acab52c7-be6f-4343-8f77-bb53763502b8"}]},"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":"大気中メタンの炭素同位体比測定とその挙動解析(I): 微量メタンの濃縮・分離とその炭素同位体比測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大気中メタンの炭素同位体比測定とその挙動解析(I): 微量メタンの濃縮・分離とその炭素同位体比測定","subitem_title_language":"ja"}]},"item_type_id":"9","owner":"17","path":["1223"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-04-28"},"publish_date":"2010-04-28","publish_status":"0","recid":"11349","relation_version_is_last":true,"title":["大気中メタンの炭素同位体比測定とその挙動解析(I): 微量メタンの濃縮・分離とその炭素同位体比測定"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-11-16T00:23:45.770170+00:00"}
