In this study, it was found that when the pH of the mobile phase was 5.5, a significant tailing of the alminium chelate was observed, whereas when the pH was 2, a marked improvement of the elution was attained. These results were interpreted in terms of a silanol masking effect: when an acidic mobile phase is employed, protonation of the silanol groups on the surface is maintained, while eliminating the strong interaction between the cationic chelate and the stationary phase. The addition of sodium chloride in the eluent can also be used to eliminate peak tailing of the cationic chelate. Based on these results, the underlying immobilization mechanism of the aluminium chelate. Based on these results, the under-lying immobilization mechanism of the aluminium chelate on the C_18-bonded silica thin layer is explained by an electrostatic interaction between the cationic aluminium chelate and deprotonated silanol groups on the solid surface. The example in this study should provide valuable information to improve the separation quality of cationic solutes in HPLC.","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_other_language_22":{"attribute_name":"その他の言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人日本分析化学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05251931","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"KURASAWA, Takashi"},{"subitem_text_value":"YOTSUYANAGI, Takao"},{"subitem_text_value":"KANEKO, Emiko"},{"subitem_text_value":"SAITO, Shingo"},{"subitem_text_value":"HOSHI, Suwaru"},{"subitem_text_value":"AKATSUKA, Kunihiko"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1002494"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"東北大学大学院工学研究科(現 : 野村證券株式会社)"},{"subitem_text_value":"東北大学大学院工学研究科:宮城工業高等専門学校"},{"subitem_text_value":"北見工業大学工学部"},{"subitem_text_value":"北見工業大学工学部"},{"subitem_text_value":"北見工業大学大学院工学研究科"},{"subitem_text_value":"北見工業大学大学院工学研究科"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Department of Applied Chemistry, Graduate School of Engineering, Tohoku University(Present : The Nomura Securities Co.
