 Slide 12 Shows the relative percentage of each the compound in the start mixture ( shown in yellow, note that many of the percentages are so low as to be not noticeable ), plus the % of the compound in the isolated/purified Flash Chromatography separation ( shown in blue ) and the same for the Quattro gradient HSCCC separation ( shown in red ). It will be noted that in the vast majority of cases Quattro CCC purification yielded both higher recovery and higher purity than Flash Chromatography. This result is even more remarkable if one considers that the chromatographers doing the research had over 40 years experience with Flash Chromatography with this and similar samples and only a few months experience with the Quattro CCC after a training period with the author.
