Abstract

A new addition method that may be useful for quantitative spectrochemical analysis of several elements was investigated. Though an exact solution of the problem was not possible, some approximate solutions were obtained by abolishing the extrapolation technique that is customarily employed in the usual addition method and taking into account the slopes of two analytical curves belonging to an added and an unadded series, respectively. The experiment shows that this new method may be useful in selected instances even though it sometimes gives a considerably large error of about 30%.
