Figure 2
O 1s spectra from a 19 µm liquid jet of 0.05 M NaCl collected with a photon energy of 700 eV: (a) without a pinhole and (b) with a 30 µm pinhole in the intermediate focus of the beamline. Both spectra are acquired using a 10 µm exit slit on the beamline. The peaks corresponding to the liquid jet, O 1s(liq), and from gas phase, O 1s(gas), are labeled only in (a). |
