  A hyphenated technique is an on-line combination of a separation technique and one or more spectroscopic detection techniques. These techniques have received ever-increasing attention in pharmaceutical analysis over conventional chromatographic or classical spectroscopic techniques for both qualitative and quantitative analysis of unknown compounds in complex and varied matrices with a minimum of preparation.

  The hyphenation involves linking liquid chromatography (LC), usually a high performance liquid chromatography (HPLC), gas chromatography (GC), or capillary electrophoresis (CE) to spectroscopic detection techniques such as photodiode array (PDA) UV-Vis absorbance, Fourier-transform infrared (FTIR), nuclear magnetic resonance (NMR), mass spectroscopy (MS), inductively coupled plasma (ICP)- mass spectroscopy. These couplings result in the introduction of any of these modern hyphenated techniques, namely GC or LC-PAD, GC or LC-FTIR, GC or LC-NMR, GC or LC-MS and CE-MS etc. Furthermore, the coupling of separation and detection techniques could entail more than one separation or detection techniques in the hyphenation process. For instance, LC-PDA-FTIR, LCPDA-NMR-MS, LC-PDA-MS, LC-MS-MS, LC-NMR-MS and GC-ICPMS and the like could be coupled.
