Spark-source mass spectrometry using the peak switching mode of electrical detection has been used for the quantitative analysis of V, Cr, Mn, Fe, and Ni in titanium dioxide pigments. Standards of differing histories form linear calibration curves down to 0.4 ppm when a source coldfinger was used to condense hydrocarbon species. An over-all relative standard deviation of 12.7% was obtained for V, Cr, Mn, Fe, and Ni in the TiO2 standards.
