Chromatographic Simulation of the Effect of a Polyvalent Counter Ion on Retention Behavior and Peak Intensity of Sulfate Nishimura, Masayuki Hayashi, Morimasa Yamamoto, Atsushi 40115267 Hayakawa, Kazuichi 50009164 Miyazaki, Motoichi Copyright © The Japan Society for Analytical Chemistry The effect of a mobile phase polyvalent counter ion on the retention behavior and peak intensity of sulfate in non- suppressed ion chromatography was quantitatively studied using a chromatogram simulation method. In this study, both indirect photometric detection (IPD) method and conductometric detection (CD) method were evaluated. With the IPD method, the retention of sulfate was observed to decrease in the presence of the polyvalent counter ion (Trien) without any change in peak intensity. With the CD method, however, peak intensity of sulfate decreased and, under some conditions, gave a negative peak in simulation as was also observed in actual experiments. The present work demonstrates the possibility of predicting the effect of a polyvalent counter ion on sulfate retention without resorting to physical experiments. 日本分析化学会 = The Japan Society for Analytical Chemistry 1995-01-01 2017-10-04 eng journal article VoR http://hdl.handle.net/2297/44527 https://kanazawa-u.repo.nii.ac.jp/records/15187 10.2116/analsci.11.755 https://www.jstage.jst.go.jp/browse/analsci http://www.jsac.jp/ AA10500785 0910-6340 Analytical Sciences 11 5 755 758 https://kanazawa-u.repo.nii.ac.jp/record/15187/files/PH-PR-HAYAKAWA-K-755.pdf application/pdf 232.4 kB 2017-10-04
