Use of a mixed argon-hydrogen-tetrafluoromethane carrier gas for the analysis of nickel materials by electrothermal vaporization coupled to inductively coupled plasma optical emission spectrometry

Electrothermal vaporization (ETV) coupled to inductively coupled plasma optical emission spectrometry (ICPOES) was used to directly determine minor and trace elements in nickel (Ni) foam samples. In addition to 9 mL min −1 CF 4 reaction gas, 20 mL min −1 H 2 was added to the carrier gas to further e...
