文摘

Common methods are not suitable for a reliable determination of Cr(VI) in organic coatings on steel. Our proposed method is a combination of XPS and ultra-low-angle microtomy (ULAM). The results allow referring to legal regulations of the Cr(VI) concentration. For this method no accurate sample parameters are required.
