In the PIEI mode, molecular cations appeared in all compounds, though they were small. In the PICI mode, [M+1]+ quasi-molecular cations together with [M+C2H5]+ ions and many fragment ions, appeared. In the NICI mode. the number of peaks was much less than that in both positive modes; intense molecular anions were observed for nifedipine, nisoldipine and nitrendipine, which seem very useful for sensitive and specific detection by gas chromatography (GC)/mass spectrometry (MS) in the NICI mode. Nifedipine, nisoldipine and nitrendipine, which had been added to body fluid samples, could be rapidly extracted by the use of Sep-Pak C18 cartridges. They could be detected both with and without photodecomposition by capillary GC with a DB-1 column, with satisfactory separation and recovery. We recommend the analytical method with photodecomposition, because no special care for light is required during the whole procedure.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_3_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本法中毒学会","subitem_publisher_language":"ja"}]},"item_3_rights_7":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright 日本法中毒学会","subitem_rights_language":"ja"},{"subitem_rights":"本文データは日本法中毒学会の許諾のもと掲載しています。","subitem_rights_language":"ja"}]},"item_3_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09159606","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_32":{"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":"Kumazawa, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3682","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sato, Keizo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3683","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Seno, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3684","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Osamu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"3685","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-08-27"}],"displaytype":"detail","filename":"FT-11-37.pdf","filesize":[{"value":"511.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"FT-11-37.pdf","url":"https://hama-med.repo.nii.ac.jp/record/1652/files/FT-11-37.pdf"},"version_id":"6da3cd89-411a-454a-80bf-94da582f5ad1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Nifedipine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Nisoldipine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Nitrendipine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Dehydronitrosonifedipine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Dehydronitrosonisoldipine","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Photodecomposition","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mass spectrometry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Gas chromatography","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Sep-Pak C18 cartridges","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Negative ion","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"POSITIVE AND NEGATIVE ION MASS SPECTROMETRY AND RAPID EXTRACTION WITH SEP-PAK C18 CARTRIDGES FOR DIHYDROPYRIDINE CALCIUM ANTAGONISTS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"POSITIVE AND NEGATIVE ION MASS SPECTROMETRY AND RAPID EXTRACTION WITH SEP-PAK C18 CARTRIDGES FOR DIHYDROPYRIDINE CALCIUM ANTAGONISTS","subitem_title_language":"en"}]},"item_type_id":"3","owner":"4","path":["11"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2013-08-27"},"publish_date":"2013-08-27","publish_status":"0","recid":"1652","relation_version_is_last":true,"title":["POSITIVE AND NEGATIVE ION MASS SPECTROMETRY AND RAPID EXTRACTION WITH SEP-PAK C18 CARTRIDGES FOR DIHYDROPYRIDINE CALCIUM ANTAGONISTS"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-08-02T03:48:29.357318+00:00"}
