For selecting the separation column, sulfobetaine-type zwitterionic surfactant (CHAPS)-modified silica C_<18> and silica C_<30> columns, and a zwitterionic stationary phased column HILIC were compared for anion separations. The retention order of the analyte anions was SO_4^<2−><Cl^−<NO_3^−<I^−<ClO_4^−  without regard to the types of the columns, depending on the nature of EIC separation. However, the resolutions were different, because the anion separations by EIC were strongly affected by the hydrophobicity of the stationary phase. As a result, the CHAPS-modified silica C_<18>  column was the most suitable as a separation column in EIC in terms of the peak resolution and the retention time. In contrast, cation separations using the CHAPS-modified silica C_<18> column with a water eluent were in the order of monovalent cations (Li^+, Na^+, K^+ and NH_4^+) < divalent cations (Mg^<2+> and Ca^<2+>). This fact means that the sulfobetain-type zwitterionic stationary phase has much higher selectivity for anions than for cations. Moreover, a pre-column (cation-exchange resin in the Li^+-form for anion separations, and anion-exchange resin in the Cl^−-form for cation separations) was connected in tandem before the separation column, in order to make uniform the counter ion for analyte ions and to apply this method to real water samples. Under the optimized conditions, the linearity of the calibration graph, the detection limit, and the reproducibility for the common anions were tested, and satisfactory results was obtained for all common anions. The potentiality of EIC was demonstrated in practical applications to the determination of common anions (SO_4^2−, Cl^−, NO_3^− and HCO_3^−) and hardness in river water.","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"4343","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MASUDA, Wakako"}]},{"nameIdentifiers":[{"nameIdentifier":"4344","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KOZAKI, Daisuke"}]},{"nameIdentifiers":[{"nameIdentifier":"4345","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NAKARANI, Nobutake"}]},{"nameIdentifiers":[{"nameIdentifier":"4346","nameIdentifierScheme":"WEKO"}],"names":[{"name":"GOTO, Ryozo"}]},{"nameIdentifiers":[{"nameIdentifier":"4347","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MORI, Masanobu"}]},{"nameIdentifiers":[{"nameIdentifier":"4348","nameIdentifierScheme":"WEKO"}],"names":[{"name":"FUGETSU, Bunshi"}]},{"nameIdentifiers":[{"nameIdentifier":"4349","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TANAKA, Kazuhiro"}]}]},"item_2_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本分析化学会"}]},"item_2_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2116/bunsekikagaku.58.311","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_10":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0525-1931","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_19":{"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":"増田, 和香子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小崎, 大輔"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"NAKATANI, Nobutake","creatorNameLang":"en"},{"creatorName":"中谷, 暢丈","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"後藤, 良三"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森, 勝伸"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"古月, 文志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田中, 一彦"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-09-14"}],"displaytype":"detail","filename":"S-844_Nakatani.pdf","filesize":[{"value":"871.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"S-844_Nakatani.pdf","url":"https://rakuno.repo.nii.ac.jp/record/1813/files/S-844_Nakatani.pdf"},"version_id":"4d6acbce-b61a-47ba-a249-b717d48e7c4e"}]},"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":"両性イオン界面活性剤を修飾したシリカ-C_<18>カラムと水溶離液を用いる陰イオンと陽イオンの導電率検出静電型イオンクロマトグラフィー","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"両性イオン界面活性剤を修飾したシリカ-C_<18>カラムと水溶離液を用いる陰イオンと陽イオンの導電率検出静電型イオンクロマトグラフィー"}]},"item_type_id":"2","owner":"3","path":["24"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-03-31"},"publish_date":"2011-03-31","publish_status":"0","recid":"1813","relation_version_is_last":true,"title":["両性イオン界面活性剤を修飾したシリカ-C_<18>カラムと水溶離液を用いる陰イオンと陽イオンの導電率検出静電型イオンクロマトグラフィー"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-31T01:01:35.412226+00:00"}
