Excellent ion beam sensitivity was demonstrated with the detection of 1 mBq (0.2 fg) 90Sr on a Daly ion-counting system. The abundance sensitivity for the 90Sr/88Sr ratio was 2.1×10 10 and this could ensure measurement of 100 Bq·kg 1 (19 fg·g 1) 90Sr in an environmental sample with 100 µg·g 1 stable strontium concentration. For analytical method validation, 90Sr was determined in two certified reference materials e.g. wild berry (IRMM-426) and freshwater lake sediment (NIST-4354) for the first time in the history of TIMS. This mass spectrometry method is faster than conventional radiometric techniques; however, interference from 90Zr and peak tailing on the higher mass side from 88Sr must be considered for a reliable 90Sr determination.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Chemical Society"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1021/acs.analchem.8b05184","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0003-2700","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kavasi, Norbert"}],"nameIdentifiers":[{"nameIdentifier":"772980","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kumar Sahoo, Sarata"}],"nameIdentifiers":[{"nameIdentifier":"772981","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kavasi, Norbert","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"772982","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sahoo, Sarata","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"772983","nameIdentifierScheme":"WEKO"}]}]},"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":"Method for Sr-90 Analysis in Environmental Samples Using Thermal Ionization Mass Spectrometry with Daly Ion-Counting System","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Method for Sr-90 Analysis in Environmental Samples Using Thermal Ionization Mass Spectrometry with Daly Ion-Counting System"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-21"},"publish_date":"2019-01-21","publish_status":"0","recid":"73402","relation_version_is_last":true,"title":["Method for Sr-90 Analysis in Environmental Samples Using Thermal Ionization Mass Spectrometry with Daly Ion-Counting System"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-16T00:25:51.186102+00:00"}
