The analysis

The claim describes the standard, textbook operational definition of how quantitative XPS is performed. The retrieved literature confirms this repeatedly (e.g., ISO 18118 standard on RSFs, standard quantification approaches). Therefore, the verdict is COMMON_KNOWLEDGE, with supporting papers appropriately cited.
