16. Strictly speaking this plasma is being used as the excitation source for optical emission spectroscopy and is therefore only a component of the detection system.
17. The assignments to each of the emission lines monitored in this experiment are noted in the figure with the exception of those at 357 nm and 336 nm whose assignments remain ambiguous.

19. Retention times measured relative to the interruption of the first plasma (220 s).
20. Closer inspection of the frontal system actually indicates that there is a fourth component (although significantly less intense) whose step edge can be observed at approximately 165 s (retention time 155 s, Figs. 5 and 6). A similar addition to the convolution diagram (Fig. 9(d)) could be made for this species.
