Read the full article
Ellipsometric method of standard elements certification for spectrophotometrical equipment has been considered. Comparison of certification results of standard elements for spectrophotometrical equipment by ellipsometric method with the data obtained by impulse photometry method has been carried out. Particularities of the temporal change for standard elements photometric characteristics in petroleum etherand in the atmosphere have been determined under normal conditions.
