Methods by using a broad pH range column(Gemini NX C18,4.6mm×150mm,5μm),basic mobile phase which was[H_2O-ammonia-glacial acetic acid] (96:3.6:0.4)-methanol,the related substances in etimicinsulfate were separated and detected by electrospray ionization and positive ion monitoring,the ESI ion source condition was following: temperature is 350℃,nebulizing pressure is 50 psi,dry gas flow is 10 L /min.some related substances in etimicinsulfate were identified by comparing the retention time in chromatography,~+ spectrum and MS~2 spectrum with reference substances\',the others which haven\'t reference substances were identified or speculated by analyzing their MS~2 fragmentation with the help of a rule summarized from the MS~2 fragmentation of gentamicin C1a,micronomicin and etimicin.Results nineteen related substances in etimicinsulfate were separated and detected.

方法利用宽pH范围的Gemini NX C18(4.6mm×150mm，5μm)色谱柱，在碱性条件下，以[水-氨水-冰醋酸(96：3.6：0.4)]-甲醇(70：30)为流动相，直接分离各组分；并用HPLC-ESI-MS~2检测样品中各组分，质谱条件：ESI离子源，离子源温度350□，雾化室压力50 psi，干燥气流速10 L/min，正离子检测方式；对有对照品的有关物质采用比对有关物质与对照品的色谱保留时间、准分子离子的质荷比及二级质谱方法进行鉴定，无对照品的有关物质，则是先通过解析庆大霉素Cla、小诺霉素、依替米星的二级质谱，对该类化合物的二级质谱裂解规律进行归纳，并以此推测未知新化合物进行结构，再用推测的结构对二级质谱进行解析，如所有的碎片离子均合理解释，表明推测合理。
