Chloride ions can result from contamination, especially if the sample has been handled without.When quantifying chlorine fit in this way, turn off the Cl2p 1/2 components for each.Spin-orbit components one set for each chemical state. Example below from a sample with chloride and organic Cl.Which has one component for each chemical state). Each chemical state has two spin-orbit split peaks (compared to oxygen, for example,.Resolution spectrum to confirm assignment. Check for presence of Cl2s peak in survey spectrum and spin-orbit splitting in Cl2p high.For chlorine-containing polymers which may be sensitive to X-ray exposure, acquire C1sĪnd Cl2p regions first, before moving onto survey and/or other elemental regions.Polymer materials containing Cl may degrade during X-ray irradiation or argon ion sputtering,.In the presence of high selenium or arsenic concentrations, acquire Cl2s as well as (or instead of).Binding energies of common chemical states:
