The optimized solvent extraction, which involved freezing and crushing the PP, results in a good recovery, 89±4 and 97±8% for 0.5 wt% of the added antioxidant, tetrakis[methylene3-(3,5-di-t-butyl-4-hydroxyphenyl)propionate]methane (commercial name; Irganox1010) in laboratory-produced and commercial PP composites, respectively. The positive ion measurements in DIOS and TiO2-SALDI-MS yielded sodium adduct ions without any interference from other signals. Using an internal standard with a similar structure, a good calibration curve linearity was established in the Irganox1010 concentration range of 0.01-2.0 mg/mL in PP, which was sufficient for monitoring the plastic additives. However, TiO2-SALDI-MS was superior to DIOS-MS in terms of mass resolution and easiness of sample preparation. A solvent extraction method followed by TiO2-SALDI-MS appears to be a anticipated method for the analysis of additives in insoluble plastics.","subitem_description_type":"Other"}]},"item_9_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"27115","nameIdentifierScheme":"WEKO"}],"names":[{"name":"大坂, 一生"}]},{"nameIdentifiers":[{"nameIdentifier":"27116","nameIdentifierScheme":"WEKO"}],"names":[{"name":"奥村, 晃司"}]},{"nameIdentifiers":[{"nameIdentifier":"27117","nameIdentifierScheme":"WEKO"}],"names":[{"name":"三宅, 直毅"}]},{"nameIdentifiers":[{"nameIdentifier":"27118","nameIdentifierScheme":"WEKO"}],"names":[{"name":"渡辺, 健宏"}]},{"nameIdentifiers":[{"nameIdentifier":"27119","nameIdentifierScheme":"WEKO"}],"names":[{"name":"野崎, 和吉"}]},{"nameIdentifiers":[{"nameIdentifier":"27120","nameIdentifierScheme":"WEKO"}],"names":[{"name":"川崎, 英也"}]},{"nameIdentifiers":[{"nameIdentifier":"27121","nameIdentifierScheme":"WEKO"}],"names":[{"name":"荒川, 隆一"}]}]},"item_9_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Mass Spectrometry Society of Japan"}]},"item_9_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.5702/massspec.58.123","subitem_relation_type_select":"DOI"}}]},"item_9_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1254271X","subitem_source_identifier_type":"NCID"}]},"item_9_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13408097","subitem_source_identifier_type":"ISSN"}]},"item_9_text_35":{"attribute_name":"出版者（他言語）","attribute_value_mlt":[{"subitem_text_value":"日本質量分析学会"}]},"item_9_version_type_17":{"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":"Osaka, Issey"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okamura, Koji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Miyake, Naoki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Watanabe, Takehiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nozaki, Kazuyoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kawasaki, Hideya"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Arakawa, Ryuichi"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-23"}],"displaytype":"detail","filename":"KU-1100-20100000-01.pdf","filesize":[{"value":"279.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KU-1100-20100000-01.pdf","url":"https://kansai-u.repo.nii.ac.jp/record/11541/files/KU-1100-20100000-01.pdf"},"version_id":"896b9efe-83fc-4057-946a-1702794b848f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"SALDI","subitem_subject_scheme":"Other"},{"subitem_subject":"DIOS","subitem_subject_scheme":"Other"},{"subitem_subject":"MALDI","subitem_subject_scheme":"Other"},{"subitem_subject":"Antioxidant additive","subitem_subject_scheme":"Other"},{"subitem_subject":"Quantitation","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":"Quantitative Analysis of an Antioxidant Additive in Insoluble Plastics by Surface-Assisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) Using TiO2 Nanoparticles","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Quantitative Analysis of an Antioxidant Additive in Insoluble Plastics by Surface-Assisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) Using TiO2 Nanoparticles"}]},"item_type_id":"9","owner":"1","path":["1597"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-02-02"},"publish_date":"2012-02-02","publish_status":"0","recid":"11541","relation_version_is_last":true,"title":["Quantitative Analysis of an Antioxidant Additive in Insoluble Plastics by Surface-Assisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) Using TiO2 Nanoparticles"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-05-15T14:40:50.454207+00:00"}
