    Traces from the Thomson parabola spectometer observed under six experimental conditions: a no-heating condition (a) and five heating conditions, namely, 50 °C (b), 80 °C (c), 110 °C (d), 130 °C (e), and 150 °C (f). (g) Equilibrium coverage calculated from the Langmuir adsorption model. (h) Ion spectra for the no-heating condition. (i) Ion spectra for the 150 °C heating condition.
