The MALDI mass spectra　indicated that the polymers have a repeated unit of (CH_2CH_2O) in the structure and contain small amounts of octyl- and decyl-phe-nolpolyethoxylate contaminants. The　average molecular weights of the polymers obtained from the mass spectra were　consistent with those of GPC measurements. Li^+ among alkali metal ions was found to be the best cationizing agent in PSD　experiments. The PSD spectra suggested that the alkylphenol moiety in the end group of nonylphenolpolyethoxylate polymers contains alkyl structure of C_6H_<13-> group.","subitem_description_type":"Other"}]},"item_9_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"27553","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ohmoto, Masayoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"27554","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Okuno, Shoji"}]},{"nameIdentifiers":[{"nameIdentifier":"27555","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Arakawa, Ryuichi"}]}]},"item_9_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本分析化学会"}]},"item_9_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00222633","subitem_source_identifier_type":"NCID"}]},"item_9_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05251931","subitem_source_identifier_type":"ISSN"}]},"item_9_version_type_17":{"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":"大本, 将義"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"奥野, 昌二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"荒川, 隆一"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-23"}],"displaytype":"detail","filename":"KU-1100-20040605-09.pdf","filesize":[{"value":"311.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-20040605-09.pdf","url":"https://kansai-u.repo.nii.ac.jp/record/11605/files/KU-1100-20040605-09.pdf"},"version_id":"434ec414-02ff-454d-acc1-10ab5b0b9f34"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"matrix assisted laser desorption/ionization","subitem_subject_scheme":"Other"},{"subitem_subject":"post source decay","subitem_subject_scheme":"Other"},{"subitem_subject":"surfactant","subitem_subject_scheme":"Other"},{"subitem_subject":"alkylphenolpolyethoxylate","subitem_subject_scheme":"Other"},{"subitem_subject":"cationizing agents","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"マトリックス支援レーザー脱離イオン化質量分析法におけるポストソース分解法によるノニルフェノールポリエトキシレートの構造解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"マトリックス支援レーザー脱離イオン化質量分析法におけるポストソース分解法によるノニルフェノールポリエトキシレートの構造解析"}]},"item_type_id":"9","owner":"1","path":["1597"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-02-02"},"publish_date":"2012-02-02","publish_status":"0","recid":"11605","relation_version_is_last":true,"title":["マトリックス支援レーザー脱離イオン化質量分析法におけるポストソース分解法によるノニルフェノールポリエトキシレートの構造解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:14:36.409045+00:00"}
