高效液相色谱－核磁共振（ＨＰＬＣ－ＮＭＲ）在线联用技术是同时进行未知混合物的分离和结构鉴定的最好手段之一。详细介绍了在ＨＰＬＣ－ＮＭＲ联用技术中１Ｈ谱的分辨率、检测限和多重溶剂峰抑制的最新进展，并简要评述了其它分离方法与ＮＭＲ联用情况
High Performance Liquid Chromatography - Nuclear Magnetic Resonance (HPLC-NMR) online technology is one of the best ways to carry out the separation and structural identification of unknown mixtures simultaneously. The recent progress in the resolution, detection limit and multiple solvent peak suppression of 1H spectroscopy in HPLC-NMR was introduced in detail, and the other separation methods were briefly reviewed
