The relative sensitivity coefficients for negative ions of 15 elements contained in compressed aluminium powder electrodes were measured by spark source mass spectroscopy. The relative sensitivity coefficients for the halogens and group VIB elements were found to be the largest, the difference of relative sensitivity coefficients between the elements being larger than in the case of positive ion relative sensitivity coefficients. The logarithm of the relative sensitivity coefficients of negative ions are linearly correlated to the electron affinities of the elements.
