- Abstract:The document specifies a method for testing hydrofluoric acid for the metal traces of cobalt (Co), chromium (Cr), copper (Cu), iron (Fe), and nickel (Ni) relevant to semiconductor technology. Emission spectroscopy with plasma excitation (for example, inductively coupled plasma (ICP) or direct current plasma (DCP)) is used for the determination. The range of application covers trace element mass fractions from 1 ng/g to 1000 ng/g.
