A zwitterionic surfactant (sulfobetaine-type) and a nonionic surfactant (polyoxyethylene-type) were used for a stationary-phase modification. When aqueous electrolyte solutions with concentrations of sub-mM to several mM were used as a mobile phase, the zwitterionic surfactant coated on the ODS surface exhibited unique separation selectivity for ionic species, while the nonionic surfactant coated on the ODS might have formed a hydrophilic network over the ODS surface and restricted matrix proteins from adsorbing on the stationary phase. Consequently, the mixed surfactant-modified column system allowed an efficient ion chromatographic separation of inorganic anions as well as a size-exclusive removal of column-fouling proteins. This separation system was applied to the direct injection determination of UV-absorbing anions in human saliva. The detection limits for nitrite, nitrate, iodide and thiocyanate were 3.1, 2.7, 4.5 and 25 \u00b5M, respectively, with UV detection at 210 nm (injection volume; 20 \u00b5l), and their relative standard deviations for 5 replicate measurements of saliva samples spiked with 100 \u00b5M each of those anions were 1.4, 0.9, 2.2 and 5.5%, respectively.", "subitem_description_type": "Abstract"}]}, "item_10_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/8754"}]}, "item_10_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u65e5\u672c\u5206\u6790\u5316\u5b66\u4f1a"}]}, "item_10_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://dx.doi.org/10.2116/analsci.21.913", "subitem_relation_type_select": "DOI"}}]}, "item_10_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_10_source_id_7": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0910-6340", "subitem_source_identifier_type": "ISSN"}]}, "item_10_text_14": {"attribute_name": "\u30d5\u30a9\u30fc\u30de\u30c3\u30c8", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "HASEGAWA, Takuya"}], "nameIdentifiers": [{"nameIdentifier": "19101", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "UMEMURA, Tomonari"}], "nameIdentifiers": [{"nameIdentifier": "19102", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KOIDE, Akira"}], "nameIdentifiers": [{"nameIdentifier": "19103", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "CHIBA, Koichi"}], "nameIdentifiers": [{"nameIdentifier": "19104", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "UEKI, Yuji"}], "nameIdentifiers": [{"nameIdentifier": "19105", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "TSUNODA, Kin-ichi"}], "nameIdentifiers": [{"nameIdentifier": "19106", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "HARAGUCHI, Hiroki"}], "nameIdentifiers": [{"nameIdentifier": "19107", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2018-02-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "v21_n_8_913-916.pdf", "filesize": [{"value": "75.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 75800.0, "url": {"label": "v21_n_8_913-916.pdf", "url": "https://nagoya.repo.nii.ac.jp/record/7080/files/v21_n_8_913-916.pdf"}, "version_id": "54f395d6-77fb-429b-985c-0ea395f8b2ad"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Evaluation of an ODS Column Modified with Zwitterionic/Nonionic Mixed Surfactants and Its Application to Direct Injection Determination of Inorganic Anions", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Evaluation of an ODS Column Modified with Zwitterionic/Nonionic Mixed Surfactants and Its Application to Direct Injection Determination of Inorganic Anions"}]}, "item_type_id": "10", "owner": "1", "path": ["320/321/322"], "permalink_uri": "http://hdl.handle.net/2237/8754", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2007-09-14"}, "publish_date": "2007-09-14", "publish_status": "0", "recid": "7080", "relation": {}, "relation_version_is_last": true, "title": ["Evaluation of an ODS Column Modified with Zwitterionic/Nonionic Mixed Surfactants and Its Application to Direct Injection Determination of Inorganic Anions"], "weko_shared_id": 3}
