The ligand forms kinetically stable Ln complexes at the pre-capillary derivatizing step. It effectively avoids quenching processes of the ligand-centered fluorescence through complexation with Ln_<3+>without paramagnetic and heavy atom effects because of the distance between the chelating and the antenna moieties. During the on-capillary separation step, the mother Ln complexes competitively form ternary complexes with the auxiliary ligands, iminodiacetate and citrate, which provide different mobilities for each of the Ln_<3+> complexes. The emissively labeled Ln_<3+> complexes were efficiently separated, based on the ternary complex equilibrium. Since the carrier buffer employed was free from emissive ligands, a high signal to noise ratio was obtained. A lower detection limit of 9.1 x 10(-11) mol dm(-3) (15.6 ng dm(-3), 0.46 attomole as an amount basis) was successfully achieved typically for Lu3+ with a simple CZE mode. We propose a combination of a pre-capillary and an on-capillary complexing technique as a method that provides both high sensitivity and high resolution.","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"Royal Society of Chemistry"}]},"item_119_relation_16":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1039/b613534j http://www.rsc.org/publishing/jou","subitem_relation_type_select":"DOI"}}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00032654","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[著者版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"Saito, Shingo"},{"subitem_text_value":"Takeuchi, Shingo"},{"subitem_text_value":"Yoshimoto, Keitaro"},{"subitem_text_value":"Maeda, Mizuo"},{"subitem_text_value":"Aoyama, Masakazu"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002471"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"北見工業大学工学部工学研究科環境化学講座環境分析研究室(現 : 埼玉大学大学院理工学研究科物質科学部門)"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Department of Applied and Environmental Chemistry, Kitami Institute of Technology"},{"subitem_text_value":"Graduate School of Environmental Studies, Tohoku University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2007"}]},"item_119_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"齋藤, 伸吾"},{"creatorName":"サイトウ, シンゴ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1002471.pdf","filesize":[{"value":"268.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002471.pdf","url":"https://sucra.repo.nii.ac.jp/record/13139/files/A1002471.pdf"},"version_id":"a243641d-d143-450d-9fbd-dc64db1b7243"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Direct Fluorescent Detection of Ultratrace Lanthanide(III) Ions Complexed with Aromatic Polyaminocarboxylate Avoiding Quenching of Ligand-Centered Emission Using Capillary Zone Electrophoresis with Ternary Complexing Technique","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Direct Fluorescent Detection of Ultratrace Lanthanide(III) Ions Complexed with Aromatic Polyaminocarboxylate Avoiding Quenching of Ligand-Centered Emission Using Capillary Zone Electrophoresis with Ternary Complexing Technique"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-03-10"},"publish_date":"2008-03-10","publish_status":"0","recid":"13139","relation_version_is_last":true,"title":["Direct Fluorescent Detection of Ultratrace Lanthanide(III) Ions Complexed with Aromatic Polyaminocarboxylate Avoiding Quenching of Ligand-Centered Emission Using Capillary Zone Electrophoresis with Ternary Complexing Technique"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:40:06.162774+00:00"}
