Near- and supercritical water (SCW) has recently been shown to provide an unusual but effective tool to roughen the inner surface or manipulate the internal diameter of fused silica capillaries for analytical separation methods In this review, the to-date existing variants of instrumental arrangement for etching the fused silica capillaries with SCW are described, the currently accessible morphologies of SCW-etched capillaries are outlined, and both existing and prospective applications of the SCW-etched capillaries in analytical separations are briefly discussed. Relative merits of SCW and other agents to treat the inner surfaces of fused silica capillaries are also mentioned.

近来和超临界水（SCW）最近被证明提供了一种不寻常但有效的工具，可以使熔融石英毛细管的内表面变粗糙或控制熔融石英毛细管的内径，以进行分析分离方法。描述了用SCW蚀刻熔融石英毛细管的方法，概述了SCW蚀刻毛细管的当前可访问形态，并简要讨论了SCW蚀刻毛细管在分析分离中的现有和潜在应用。还提到了SCW和其他试剂在熔融石英毛细管内表面处理方面的相对优势。
