The non-charged reagent, TPEN, was applied to capillary zone electrophoresis (CZE) for the first time. Since complete spatial separation between the complexes and the ligand was carried out in a carrier buffer, which was free of TPEN, kinetic inertness of metal complexes was necessary for the detection in this pre-capillary method. All the nine listed metal complexes were detected: Ca^<2+>, Mg^<2+>, Al^<3+>, Fe^<3+>, and Co^<3+> complexes were undetectable. This, interestingly, suggests that those nine cations form kinetically inert tpen complexes without strong charge-charge interactions between the metal ion and the ligand. It is expected that the hard-soft-acid-base ( HSAB) principle governed the kinetics selectivity. With respect to the electrophoretic behavior, the addition of chloride ion and methanol to the carrier significantly improved the resolution. This is due to the formation of ternary complexes or ion aggregates and the solvation effect, respectively. These effects provided a satisfactory baseline resolution among the nine metal ions. An application to biological samples was demonstrated. Some metal ions in human serum and urine were successfully detected in a simple process without the need for deproteinization using a non-coated fused-silica capillary because of the differenciation in the direction of migration between organic matter and complexes.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"http://www.rsc.org/publishing/journals/AN/article.asp?doi=b417394e","subitem_description_type":"Other"}]},"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_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":"Sasamura, Satoru"},{"subitem_text_value":"Hoshi, Suwaru"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002468"}]},"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":"2005"}]},"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":[{},{}]},{"creatorNames":[{"creatorName":"Sasamura, Satoru"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"星, 座"},{"creatorName":"ホシ, スワル","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":"A1002468.pdf","filesize":[{"value":"293.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1002468.pdf","url":"https://sucra.repo.nii.ac.jp/record/13136/files/A1002468.pdf"},"version_id":"661b1123-a5ed-4f5e-9644-413477cfde63"}]},"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":"Simultaneous Detection of [metal(II)-tpen]^<2+> as Kinetically Inert Cationic Complexes Using Pre-capillary Derivatization Electrophoresis: An Application to Biological Samples","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Simultaneous Detection of [metal(II)-tpen]^<2+> as Kinetically Inert Cationic Complexes Using Pre-capillary Derivatization Electrophoresis: An Application to Biological Samples"}]},"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":"13136","relation_version_is_last":true,"title":["Simultaneous Detection of [metal(II)-tpen]^<2+> as Kinetically Inert Cationic Complexes Using Pre-capillary Derivatization Electrophoresis: An Application to Biological Samples"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-05-15T19:24:58.595268+00:00"}
