The relative sensitivity coefficient of an element in spark source mass spectrometry is defined and the coefficients of several elements in the matrices of Al, Fe, Ti and Cu are determined. The results are as follows Fe1 Mg 12.1, Si 2.0, P 3.6, Ti 1.6, V 1.4, Cr 1.4, Mn 2.0, Co 0.85, Ni 0.68, Cu 1.2 and Zn 3.1. The variations of the measurements are or - 50. No significant evidence of the matrix effect is observed. The physical meaning of the relative sensitivity coefficient is discussed and a rough correlation between the coefficient and the heat of sublimation together with the ionization potential of the element is examined.
