准确量取一定量的葡萄酒，按一定比例稀释后，逐滴通过 SPE 预处理柱，分离去除部分蛋白质和色素等疏水性有机物质，进样后使用 KOH 作为淋洗液，用离子色谱法测定葡萄酒中甜蜜素和二氧化硫。结果表明，甜蜜素和二氧化硫呈现出较好的峰形且与其他离子能较好的分离，RSD 均小于5%，回收率在91%~99%。

준학량취일정량적포도주，안일정비례희석후，축적통과 SPE 예처리주，분리거제부분단백질화색소등소수성유궤물질，진양후사용 KOH 작위림세액，용리자색보법측정포도주중첨밀소화이양화류。결과표명，첨밀소화이양화류정현출교호적봉형차여기타리자능교호적분리，RSD 균소우5%，회수솔재91%~99%。
Accurately measured a certain amount of wine,the diluted sample was pretreated by passing through filter membrane and DIONEX On GuardⅡ P & RP chromatographic column,prior to sample de-tection for the partly removal of the organic material(protein / pigment). After injection with KOH as elu-ent,ion chromatography determination of sodium cyclamate and sulfur dioxide in wine. Results showed a good peak shape and good separation from other ions in solution. RSD was less than 5% ,the spiked recov-eries ranged from 91% ~ 99% .
