摘　　要：利用微细加工技术研究在玻璃上制作电泳芯片的方法 ,测试了微管道的伏安特性曲线。在该电泳芯片上进行了注样和分离实验 ,采用激光诱导荧光法进行检测 ,利用CCD拍摄了进样和分离的全过程。分析了在电泳芯片上施加不同的电压对样品注样的影响 ,给出了FITC OH和FITCMicromachining of capillary electrophoresis chips is described. The current in channels was determined versus the voltage applied on the chip. Using laser induced fluorescence detection, the process of injection and separation on chips was recorded with charge coupled device (CCD). With defferent voltge of reservoirs on glass chips, profiles of the sample plug were studied. The elctropherogram of hydrolysis product of fluorescein isothiocyanate (FITC OH) and arginine labeled by fluorescein isothiocyante(FITC Arg) was obtained.
