Zusammenfassung: | Near ambient pressure-x-ray photoelectron spectroscopy (NAP-XPS) is a less traditional form of XPS that allows samples to be analyzed at relatively high pressures, i.e., at greater than 2500 Pa. NAP-XPS can probe moderately volatile liquids, biological samples, porous materials, and/or polymeric materials that outgas significantly. In this submission, we show the survey, Ca 2p, C 1s, O 1s, and N 1s NAP-XPS spectra of two biological samples (cuttlefish bones in their native state and implanted with nitrogen ions), which are materials that would be difficult to analyze by conventional XPS. The measurements were performed at 100 Pa in ambient air to compensate for surface charging. Peak fits of the Ca 2p, C 1s, and N 1s narrow scans are presented. |
