As for the gradient in the eluent composition, a shift in the pH is employed to control not only the electrophoretic mobility, but also the retention factor of the analytes. The dual-gradient method was shown to be effective in increasing the resolution and reducing the chromatographic period of ionized analytes. Fourteen kinds of o-phthalaldehyde labeled amino acids were separated within 8 min using DG-CEC with multistage enlargement in the applied voltage. The separation efficiency increased particularly for highly retained amino acids in the dual-gradient, as compared to those in the ordinary single-gradient for the eluent.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_10001_full_name_27":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"8722","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000050335080","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000050335080"}],"names":[{"name":"北川, 慎也"}]},{"nameIdentifiers":[{"nameIdentifier":"8644","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000050176921","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000050176921"}],"names":[{"name":"Ohtani, Hajime"}]}]},"item_10001_publisher_29":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Japan Society for Analytical Chemistry","subitem_publisher_language":"en"}]},"item_10001_relation_34":{"attribute_name":"item_10001_relation_34","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.2116/analsci.24.735"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.2116/analsci.24.735","subitem_relation_type_select":"DOI"}}]},"item_10001_source_id_30":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0910-6340","subitem_source_identifier_type":"ISSN"}]},"item_10001_source_id_32":{"attribute_name":"item_10001_source_id_32","attribute_value_mlt":[{"subitem_source_identifier":"AA10500785","subitem_source_identifier_type":"NCID"}]},"item_10001_version_type_33":{"attribute_name":"出版タイプ","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":"Sakai, Tomoharu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"18752","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakagawa, Hiroyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"9783","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitagawa, Shinya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"8722","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000050335080","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000050335080"}]},{"creatorNames":[{"creatorName":"Ohtani, Hajime","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"8644","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000050176921","nameIdentifierScheme":"NRID","nameIdentifierURI":"http://rns.nii.ac.jp/nr/1000050176921"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-01-25"}],"displaytype":"detail","filename":"AS 24_735.pdf","filesize":[{"value":"654.7 kB"}],"format":"application/pdf","license_note":"2008 c The Japan Society for Analytical Chemistry","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文_fulltext","url":"https://nitech.repo.nii.ac.jp/record/5390/files/AS 24_735.pdf"},"version_id":"21ad553a-a856-45da-91d6-87a239068536"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Dual-Gradient Capillary Electrochromatography by Varying the Mobile Phase Composition and Applied Voltage","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Dual-Gradient Capillary Electrochromatography by Varying the Mobile Phase Composition and Applied Voltage","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"91","path":["31"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-11-06"},"publish_date":"2012-11-06","publish_status":"0","recid":"5390","relation_version_is_last":true,"title":["Dual-Gradient Capillary Electrochromatography by Varying the Mobile Phase Composition and Applied Voltage"],"weko_creator_id":"91","weko_shared_id":-1},"updated":"2025-03-21T02:13:46.665896+00:00"}
