“…An alternative separation mode of chromatography is hydrophilic interaction liquid chromatography (HILIC) on a propyl-cyano column with MS detection (Zhong, Zhong, & Chen, 2007;Hubert et al, 2010;César et al, 2012;Yang, Zheng, Simpemba, Ma, & Ding, 2015). HILIC for glucosamine determination has also been reported on a propyl-amino column with refractive index detection (without derivatization; El-Saharty & Bary, 2002;Xinmin, Ruili, Zhihua, Yuanhong, & Tingfu, 2008), or with UV-vis detection after derivatization (Liang, Leslie, Adebowale, Ashraf, & Eddington, 1999).…”
