Optimization the BGE conditions for simultaneous determination of glucosamine and calcium. (a) The effect of BGE compositions. (b) The effect of . (c) The effect of Tris concentration. CE conditions: fused silica capillary (total length 40 cm, effective length 30 cm, ID 50 μm); separation voltage +20 kV; hydrodynamic injection (siphoning at 25 cm in 30 s). The selected conditions were highlighted in blue.
