“…Therefore, highly susceptible analytical methods for the simultaneous and selective detection of these three isomers are necessary. Different analytical techniques are applied for the selective, simultaneous detection of HQ, CT, and RS, such as high‐performance liquid chromatography (HPLC), [3,42,45,50,64] chemiluminescence, [37,43,47,52,65] spectrophotometry, [35,38,44,47,53] fluorescence, [17,33,39,51] gas chromatography/mass spectrometry (GC−MS), [15,22,46,51,63] pH‐based flow‐injection analysis, [29,40,57,71] capillary electrophoresis, [5,24,54,62] UV‐Vis spectroscopy, [56] colorimetry, [55,68] and electrochemical techniques [37–47,58–61,65–70] …”
