Therefore, it is impossible to distinguish whether nitrogen, oxygen, and carbon contained in the coating film are the gas components positively introduced or the inevitable components. However, the amount of the unavoidable component contained in the coating film is usually constant, and how much the introduced gas component is contained in the coating film can be regarded as a difference between the case where the gas is introduced and the case where the gas is not introduced.

For example, in Table 3, it can be considered that the difference between the oxygen incorporated in the film and the carbon is 1.1% and the difference between the carbon incorporated in the film is 8.4%.
