초록

가스 크로마토그래피(GC)와 가스 크로마토그래피(HPLC)를 이용하여 imidazoline계 양이온 계면활성제 분석을 수행하였다. 염기 가수분해와 산 가수분해 후 GC로 imidazoline ring의 original fatty acid의 alkyl chain 분포를 조사하였다. 역상 C18 분리관을 사용하고 0.1M NaClO₄가 함유된 methanol과 acetonitrile의 50:50(v/v)액을 용리액으로 할 때 imidazoline의 homologous한 total alkyl chain 분포가 HPLC에서 훌륭하게 분리되었으며, GC 결과와 좋은 일치를 보여주었다. 본 연구의 분석법으로, imidazoline계 양이온 계면활성제의 소수성 alkyl chain 분석 및 평균 분자량 결정이 가능하였으며, 전처리 필요없이 HPLC법을 이용한 imidazoline 의 검출한계는 10ng이었다.

Analysis for the imidazoline type cationic surfactants was performed by the gas chromatography(GC) and high performance liquid chromatography(HPLC). The composition of the alkyl chain distribution was investigated by GC after base/Acid hydrolysis of the imidazoline ring. The distribution of total alkyl chain was separated clearly by a Bondclone C18/NOVA-Pak C18 HPLC column using 50% acetonitrile in methanol containing 0.1M sodium perchlorate as a mobile phase. Alkyl chain distribution and average molecular weight of imidazoline type cationic surfactants were obtained based on these analytical methods. The agreement of results from GC and HPLC was good. The detection limit of imidazoline by HPLC method was 10ng without pretreatment.
