알킬처리된 실리카(ODS)칼럼을 이용하여 역상 이온쌍 크로마토그래피방법으로 방향족 술폰산들의 분리 인자를 조사하였으며 또한 분리를 시도하였다. 반대이온으로서 브롬화 도데실 트리메틸암모늄(DTAB)을 사용하였으며, 시료의 분리인자는 반대이온의 농도, 메탄올의 농도, 전해질의 종류 및 농도, 시료 분자에 붙어있는 작용기의 종류 및 위치등에 의하여 영향을 받았다. 최적 조건하에서 몇 가지 혼합시료를 분리할 수 있었다.

Dodecyltrimethylammonium bromide (DTAB) was examined as a counter-ion in the separation of aromatic sulfonic acids on alkylmodified silica (ODS) column by reversed-phase ion-pair chromatography. The capacity factor of acids was investigated and separation was attempted. The capacity factor of samples was influenced by the several factors such as a concentration of counter-ion, concentration of methanol, kinds and concentration of electrolyte in mobile phase as well as kinds and position of functional group in samples. Some mixtures of samples were able to be separated under optimum condition.
