The effects of vaporization temperature and time on the signal intensity of target analytes were investigated for platform vaporization fluorination assisted ETV–ICP-MS, and the experimental results are shown in Figs. 1 and 2, respectively. As could be seen from the vaporization curves inFig. 1, the maximal signal intensities for all target elements were achieved with the vaporization temperature higher than 2500 °C.
