Liquid Chromatography of Aromatic Sulfonic Acids by Tetramethylammonium Bromide

Tetramethylammonium Bromide를 이용한 방향족 술폰산들의 액체크로마토그래피
Hae-Beom Oh

C18 칼럼을 정지상으로 사용한 역상 액체크로마토그래피에서 수소성이 약한 tetramethylammonium bromide (TMAB)를 반대이온으로 사용하여 방향족 술폰산들의 머무름기구를 조사해 본 결과, 이온-쌍 모델이 우세하였다. 분석물질들의 용량인자는 반대이온의 종류와 농도, 메탄올과 co-anion의 농도, 분석물질속에 있는 작용기의 종류와 위치 및 이동상의 pH 등의 영향을 받았다. 최적 조건하에서 분석물질들의 혼합물을 효과적으로 분리할 수 있었다.

Ion-pair model was predominated over ion-interaction model in the retention mechanism of analytes when tetramethylammonium bromide (TMAB) was used as a counter-ion in the investigation of aromatic sulfonic acids on the reversed-phase liquid chromatography by C18 column as a stationary phase. The capacity factors of analytes were influenced by the type and concentration of counter-ions, concentrations of methanol and co-a nion, types and position of functional group, and the pH mobile phase. Components of analyte mixture could be separated under the optimum conditions by this method.
