<table>Comparison on the chromatograms at <i>m/z</i> 593.5 for one CSF sample (a) or one plasma sample (b) processed for F<sub>2</sub>-IsoPs analysis that has been used in Figure <a href="../fig4/">4</a> without (left panel) and with (right panel) additional 30-min holding of the column at 280°C at the end of data acquisition. The range of retention time corresponding to that for F<sub>4</sub>-NPs quantification is indicated by the braces although these samples were not used for F<sub>4</sub>-NPs quantification.</table>
