摘要
Glass microchips with different structures and functions were fabricated in our laboratory.The basic characteristic of the home-made microchips was evaluated,such as the quality of the etched microchannels,reproducibility of electrophoretic separation,and life time etc..The migration time RSD for Rhodamine B in the same or different microchannels were 2.31% or 2.44%,respectively.The column efficiency in the same glass microchip didn′t declined obviously until 200 consecutive running.Compared to the glass microchip made by Micralyne,the similar separation results were obtained on both kinds of microchips.Since,the cost of the home-made glass microchips is much lower, our home-made glass microchips show a great advantage(over) the commercial microchips in terms of the performance to cost.
Glass microchips with different structures and functions were fabricated in our laboratory. The basic characteristic of the home-made mierochips was evaluated, such as the quality of the etched microehannels, reproducibility of electrophoretic separation, and life time etc.. The migration time RSD for Rhodamine B in the same or different mieroehannels were 2.31% or 2.44% , respectively. The column efficiency in the same glass mieroehip didn＇t declined obviously until 200 consecutive running. Compared to the glass mieroehip made by Mieralyne, the similar separation results were obtained on both kinds of mierochips. Since, the cost of the home-made glass mierochips is much lower, our home-made glass mieroehips show a great advantage over the commercial microchips in terms of the performance to cost.
