To solve these problems, we designed a new on-line sample preparation system. The system consists of an eluting pump, a mixing TEE connector, a 10-port 2-position valve and a solid-phase extraction precolumn. The eluate from the precolumn is diluted with a weak solvent from the HPLC at the TEE connection to load low hydrophobic compounds onto the analytical column. The proposed on-line sample preparation system was successfully applied to the simultaneous analysis of 21 pesticides in river water using LC/TOF-MS. In this method, the recoveries from river water samples were 67 to 126% (mean 83%), the reproducibility (CV%) was in the range from 1.1 to 11% (mean 5.6%), the calibration curve was linear in the range from 1 ppb to 500 ppb (r > 0.999) and the detection limits (S/N = 3) were in the range from 0.0034 ppb (daimuron) to 3.3 ppb (oxine-copper). 2006 © The Japan Society for Analytical Chemistry.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan Society for Analytical Chemistry = 日本分析化学会"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2116/analsci.22.835","subitem_relation_type_select":"DOI"}}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jsac.or.jp/","subitem_relation_type_select":"URI"}},{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://japanlinkcenter.org/JST.JSTAGE/analsci/22.835","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 2006 by The Japan Society for Analytical Chemistry"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA10500785","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0910-6340","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"Sasaki, Hideki"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yonekubo, Jun"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hayakawa, Kazuichi"}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-04"}],"displaytype":"detail","filename":"PH-PR-HAYAKAWA-K-835.pdf","filesize":[{"value":"132.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"PH-PR-HAYAKAWA-K-835.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/15404/files/PH-PR-HAYAKAWA-K-835.pdf"},"version_id":"c0a536df-63a7-4035-9642-711b9bb9ddbc"}]},"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":"A new on-line sample preparation system for the liquid chromatography/time- of-flight mass spectrometry simultaneous analysis of pesticides in river water","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A new on-line sample preparation system for the liquid chromatography/time- of-flight mass spectrometry simultaneous analysis of pesticides in river water"}]},"item_type_id":"4","owner":"3","path":["1135"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-04"},"publish_date":"2017-10-04","publish_status":"0","recid":"15404","relation_version_is_last":true,"title":["A new on-line sample preparation system for the liquid chromatography/time- of-flight mass spectrometry simultaneous analysis of pesticides in river water"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T00:32:51.952567+00:00"}
