Analytical Variables Affecting Analysis of F<sub>2</sub>-Isoprostanes and F<sub>4</sub>-Neuroprostanes in Human Cerebrospinal Fluid by Gas Chromatography/Mass Spectrometry

<table>Comparison on the chromatograms for the 5 consecutive injections of the same pooled M-CSF sample processed for F<sub>4</sub>-NPs analysis (CSF-1 to CSF-5) at <i>m/z</i> 593.5 without (left panel) and with (right panel) additional 30-min holding of the column at 280°C at the end of data acquisition. For better viewing of the peaks of F<sub>4</sub>-NPs and the adjacent peaks, the chromatograms in the range of 4.8 min to 7.8 min were compared. The peaks for F<sub>4</sub>-NPs quantification are indicated by the braces.</table>
