Dr. Miyakoshi and his colleagues got sufficient results and reported identification and characterization of urushi with Pyrolysis-Gas Chromatography/Mass Spectrometry in 1995, and now their group found the difference between Japanese lacquer and Chinese lacquer followed their report in 1999. In this report, a trial of identifying urushi was done with its method.\nSamples used are as follows: originally made samples as standards, some samples taken from wooden building of 19th Century (Important Cultural Property) for specifying restoration, and some samples whose origins are not known. Analyzing Conditions were almost followed the suggestions in the reports of Dr. Miyakoshi's. Double-shot Pyrolyzer PY-2010D (Frontier Labo.,Co.,Ltd) for injection, HP5890II (Yokokawa Hewlett-Packard) for gas chromatograph, DB-1 (J&W Scientific Co., Ltd., 0.25um, 30m x i.d. 0.25mm) for separation column under continuous flow of He, split ratio 1:500, and Automass-150 (JEOL Co.,Ltd.,) for mass spectrometer were used for analysis. Sample was weighed about 20 micrograms with micro-balance and was put into platinum sample holder for injection. Pyrolyzer furnace was preheated to 400℃ and sample holder was induced to the appropriate position. After analyzing within limited condition, sample holder was taken away for re-heating up to 500℃ of furnace, then the second-stage pyrolysis succeeded after pushing sample holder to the appropriate position. Total Ion Chromatogram was collected and regulated with computer-assisted mass spectrometer.\nStandard samples and sap directly taken from the alive tree were ideally analyzed under all conditions and gave equivalent results as ones of Dr. Miyakoshi's. A genuine wooden sample of 19th Century used for roof support showed some difficulty in recognition of phenyl compounds under 400℃ pyrolysis because of deterioration suffered from exposure to the outdoor environment. Trace of alkene and alkane chains were detected in this sample under 500℃ decomposition and finally it was characterized to urushi-like compounds that had a long hydrocarbon chain of C17. Some samples from China, Thailand, Myammer and Vietnam were also examined and showed successful results for classification of provenance by chemical forms of urushi sap ingredients under 500℃ decomposition, although they were sometimes hindered by contaminating organic substances under 400℃ decomposition.","subitem_description_type":"Abstract"}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"[共同研究] 同位体を用いた産地決定法の研究―同位体・質量分析法を用いた歴史資料の研究―","subitem_heading_language":"ja"},{"subitem_heading_banner_headline":"[Collaborative Research] Provenance Studies of Cultural Properties Using Isotope Analysis―Various Studies of Cultural Properties Using Mass-Spectrometry―","subitem_heading_language":"en"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15024/00000945","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立歴史民俗博物館","subitem_publisher_language":"ja"}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"第86集 収録論文 タイトルリスト"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.rekihaku.ac.jp/outline/publication/ronbun/ronbun4/index.html#no86","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00377607","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-7400","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"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":"佐野, 千絵","creatorNameLang":"ja"},{"creatorName":"サノ, チエ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sano, Chie","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-04-01"}],"displaytype":"detail","filename":"kenkyuhokoku_086_13.pdf","filesize":[{"value":"3.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kenkyuhokoku_086_13.pdf","url":"https://rekihaku.repo.nii.ac.jp/record/962/files/kenkyuhokoku_086_13.pdf"},"version_id":"f3d07247-7d55-48e3-a716-ed82db12ec34"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"漆・漆類似物質の判別 : 四重極質量分析計による試み（3. 同位体・質量分析の様々な応用）","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"漆・漆類似物質の判別 : 四重極質量分析計による試み（3. 同位体・質量分析の様々な応用）","subitem_title_language":"ja"},{"subitem_title":"A Trial with Pyrolysis-Gas Chromatography/Mass Spectrometry for Identification of Urushi/Case Studies（3.
