Investigation of the effects of halide ions on indirect UV detection in capillary zone electrophoresis

Direct analysis of biogenic amines in water matrix by modified capillary zone electrophoresis with 18-crown-6

“…However, the detection of BAs is rather difficult due to their low volatility and lack of chromophores, and then derivatization procedure (pre-or post-column) has been usually applied. To prevent problems such as long reaction time, tedious processes, or side products associated with derivatization, a number of indirect detection methods have been reported [20][21][22][23][24]. Indirect UV-vis absorption and indirect laser-induced fluorescence (LIF) are the two most common indirect detection methods in CE [18,25].…”

“…However, derivatization may be problematic because of additional sample processing, variability of reaction completeness, instability of derivatives, and the toxicity of some reagents. To prevent these problems, a number of indirect detection methods have been reported (Gross and Yeung 1990;Beard and de Mello 2002;Choy, Jia, and Huie 2002;Huang and Chang 2003;Lista et al 2011), including indirect ultraviolet-visible absorption and indirect laser-induced fluorescence detection (LIF) (Driouich et al 2003;Chiu et al 2006;Fekete et al 2008). Although these methods are convenient and simple, sample pretreatment is usually required to reduce interferences.…”
