“…Lower peak intensities were evident in the pH range from 2 to 6, while peak intensities increased for the pH range 8 to 12. This is due to the suppression of dissociation of BAs in alkaline conditions to the non-ionic form [19]. Peak intensities compared to pH value is given in Fig.…”

“…Actually, a chemical derivatization is mandatory to allow the sensitive determination of PAs by spectroscopic techniques, as their molecular structure lacks of moieties with optical or fluorescent properties (Al-Hadithi and Saad 2011). In addition, thin layer chromatography (Lapa-Guimarães and Pickova 2004), ion mobility spectrometry (Parchami et al 2017), NMR (Shumilina et al 2016) and colorimetric methods (Morsy et al 2016), were also proposed.…”

“…Various methods to analysis of BAs have been developed such as high-performance liquid chromatography (HPLC) (Kaniou et al 2001), gas chromatography-mass spectrometry (GC-MS) (Almeida et al 2012;Park et al 2013), and ion mobility spectrometry (IMS) (Hashemian et al 2010;Parchami et al 2017;Karpas et al 2002a, b). Each of these analytical methods has advantages and disadvantages.…”
