LC-MS extracted ion chromatograms of the steroid isomers for an 11 min LC gradient (a), 12 min LC gradient (b), and 14 min LC gradient (c). A scatter plot of the resolution values for the isomers is also provided for the three different gradients, where the dotted line represents Rs = 1.0 and the dashed line represents Rs = 1.5 (d).
