摘　　要：与连续溶出相比,取样是第二消耗时间和人力的操作过程。几乎所有的溶出仪厂商以及很多的UV/HPLC分析仪器厂商都可提供自动取样器。自动取样器按照程序设定的间隔抽出溶液并收集在用于紫外测定的试管或HPLC的样品瓶中以供分析。在常规溶出仪的自动取样架上设计拉伸滑动结构,让小杯法溶出与常规溶出共用取样针,让小杯法也实现自动取样。Compared with continuous dissolution,sampling is the second time and manpower consuming operation process.Almost all dissolution instrument manufacturers and many UV/HPLC analytical instrument manufacturers can provide automatic sampler.The automatic sampler extracts the solution according to the interval set by the program and collects it in the test tube for UV determination or the sample bottle of HPLC for analysis.The tensile sliding structure is designed on the automatic sampling frame of the normal dissolution instrument,so that the mini vessel dissolution and the normal dissolution share the same sampling needles,so that the mini vessel method can also realize automatic sampling.
