“…CE in conjunction with UV-Vis absorption or fluorescence detection is convenient for the analysis of biogenic amines [21][22][23][24][25][26][27][28][29][30][31][32][33]. Having LODs at the mM or sub-mM level for aromatic and heterocyclic amines, CE with UV-Vis absorption is widely used for the analysis of samples such as foods and beverages that contain high concentrations of amines of interest [67,68].…”

“…The sensitivity of UVvisible (Vis) absorption is poor for most biogenic amines [21][22][23][24][25][26][27], especially aliphatic amines because of their low molar absorptivity [22]. Alternatively, fluorescence [28][29][30][31][32][33], electrochemical detection such as amperometry [34][35][36][37][38][39], conductometry [39][40][41], contactless conductometry [42][43][44], electrochemiluminescence (ELCL) [45,46], chemiluminescence (CL) [47][48][49], and MS [50][51][52][53][54][55] are employed for detecting low concentrations of biogenic amines. Although these detection methods provide better sensitivity than UV-Vis absorption detection, they (besides MS) commonly suffer from high selectivity.…”

This paper provides an overview on the current status of the analysis of biogenic amines by CE. The basic CE separation and detection strategies for the analysis of biogenic amines are briefly described. CZE and MEKC that provide highly efficient and reproducible analysis of biogenic amines are particularly surveyed. With respect to the detection of biogenic amines, we focus on LIF, UV-visible absorption, electrochemiluminescence, and MS. Derivatization strategies, indirect methods, and on-line concentration techniques such as field-amplified sample stacking, sweeping, and use of polymer solution are described. To show the practicality of CE, we highlight currently developed techniques for the determinations of biogenic amines in biological samples, including foods, beverages, cerebrospinal fluids, urine, and single cells.
