Abstract:  A method suitable for estimation of resolving power of spectral apparatuses is described. The resolution of five types of photographic materials used in the spectrography was determined. It was found that the resolution of the spectrograph ISP-51 depends on the photographic materials used. On the basis of investigations of relations between the spectral line intensity and the continuous spectrum, when different photographic materials are used, it has been found that it is possible to use spectrograph slits broader than normal, without bringing about deterioration of the relation between the spectral line intensity and the continuous background; consequently the absolute detection power of the spec trochemical analysis can be improved. Dependence of the intensity of the spectral line and of the continuous background on the slit width was also studied at different focal distances of the spectrograph camera.
