摘　　要：采用一种简便的涂层方法,成功制做了涂层毛细管,替代进口。以聚乙烯醇和柠檬酸为原料配制涂层液,采用物理涂层法涂敷干燥。所制备的涂层管使用pH范围宽,达到了较好地防止毛细管壁对蛋白质样品吸附效果,避免了峰形拖尾现象。A coated capillary was fabricated by using a simple method. It means that the homemade coated capillary instead of import ones is available. The coating liquid contained polyvinyl alcohol and citric acid, and was coated physically. The homemade coated capillary can be used for wide pH range, reaches a good effect of preventing protein absorption on capillary wall.
