Seeking the difference between the two characteristics of XPS and ICP

The ICP accuracy is really high, XPS and it are not in the order of magnitude

XPS generally can only be used to analyze the most deepest surface elements but a few nanometers, and its quantitative accuracy is not as good as ICP-AES. Your ICP refers to this, and the chemical shift of XPS can solve the structure like NHR.Understand

The resolution of XPS has no ICP, although it is an elemental content, but ICP is more accurate, the best is still doing Ha ICP.

Some elements are suitable for ICP (accurate), and some are suitable for XPS (semi -quantitative). In addition, XPS can also analyze the element price state
