N3? in diluted biological fluids was reacted with NaAuCl4 to produce Au(N3)2?, which was extracted with octanol. Five microliters of the extract were flow-injected into an electrospray ionization tandem mass spectrometric instrument. Quantification of N3? was performed by selected reaction monitoring of the product ion Au(N)(N3) ? at m/z 253 which was derived from the precursor ion Au(N3)2? at m/z 281, using 50 μL of aqueous solution within 10 min. This method was found to be linear up to 10?5 M, to have a limit of quantification of 10?7 M, a limit of detection of 3.0×10?8 M, and a coefficient of variation of ≦ 10 % at 10?7 M. In case of urine, 50 μL of urine were spiked with N3?, this was diluted to10-fold and passed through 1 mL of a resin and finally diluted to 100-fold of the original. This method was linear up to 10?3 M, had a limit of quantification of 10?5 M, a limit of detection of 3.0×10?6 M, and coefficient of variation ≦ 8.8 % for an original urine concentration of 10?5 M. The practical applicability of this method was checked by diluting 1 μL of a suspected suicide victim’s gastric fluid 20,000-fold and 1 μL of the victim’s urine 5,000-fold and then measuring the N3? levels. These levels were found to be (7.5±1.0)×10?2 M and (3.2±0.4)×10?3 M, respectively.","subitem_description_type":"Abstract"}]},"item_3_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer"}]},"item_3_relation_26":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"22370586","subitem_relation_type_select":"PMID"}}]},"item_3_relation_28":{"attribute_name":"出版社DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s00216-012-5848-3","subitem_relation_type_select":"DOI"}}]},"item_3_rights_7":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"The final publication is available at Springer via http://dx.doi.org/10.1007/s00216-012-5848-3."}]},"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_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Minakata, Kayoko"}]},{"creatorNames":[{"creatorName":"Nozawa, Hideki"}]},{"creatorNames":[{"creatorName":"Yamagishi, Itaru"}]},{"creatorNames":[{"creatorName":"Gonmori, Kunio"}]},{"creatorNames":[{"creatorName":"Hasegawa, Koutaro"}]},{"creatorNames":[{"creatorName":"Suzuki, Masako"}]},{"creatorNames":[{"creatorName":"Watanabe, Kanako"}]},{"creatorNames":[{"creatorName":"Suzuki, Osamu"}]}]},"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":"abc-403-1793.pdf","filesize":[{"value":"5.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"abc-403-1793.pdf","url":"https://hama-med.repo.nii.ac.jp/record/2770/files/abc-403-1793.pdf"},"version_id":"c57d0262-e7b3-4e90-99d7-f2bd2ca05062"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Azide","subitem_subject_scheme":"Other"},{"subitem_subject":"Gold","subitem_subject_scheme":"Other"},{"subitem_subject":"Electrospray ionization","subitem_subject_scheme":"Other"},{"subitem_subject":"Tandem mass spectrometry","subitem_subject_scheme":"Other"},{"subitem_subject":"Gastric fluid","subitem_subject_scheme":"Other"},{"subitem_subject":"Urine","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":"Determination of azide in gastric fluid and urine by flow-injection electrospray ionization tandem mass spectrometry","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Determination of azide in gastric fluid and urine by flow-injection electrospray ionization tandem mass spectrometry","subitem_title_language":"en"}]},"item_type_id":"3","owner":"4","path":["11"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2015-11-20"},"publish_date":"2015-11-20","publish_status":"0","recid":"2770","relation_version_is_last":true,"title":["Determination of azide in gastric fluid and urine by flow-injection electrospray ionization tandem mass spectrometry"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-08-02T05:06:39.162233+00:00"}
