Capillary NMR detection in separation science.

This review deals with the current status of important separation techniques using capillary NMR detection. The advantages and disadvantages of the different hyphenated methods are discussed referring to a specific application. The use of Capillary-HPLC-NMR is demonstrated on an identification method of two bixin stereoisomers. The huge advantages using an HPLC-SPE-NMR method for structure determination are explained and discussed. Furthermore, two uncommon coupling techniques such as CE-NMR and GC-NMR are described in this review article.
