| Abstract: | It was to establish a quantitative analysis method of glufosinate-ammonium(TC&AS) by Ion Chromatography(IC).Methods] The active ingredient of glufosinate-ammonium was analyzed quantitatively with external standard method using AS-11 ion column(including AG-11 guard column),conductivity detector and 8 mmol/L potassium hydroxide aqueous solution as mobile phase.Results] The linear correlation coefficient was 0.9995(50-250 mg/L),standard deviations was less than 0.08,coefficient of variation was less than 0.... |
