Conclusions
On the basis of the results obtained, the gas discharge sources DKSSh-200 and SVD-120A can be recommended for use in automatic photoabsorption analyzers under the obligatory proviso of construction of the instrument according to the two-channel setup.
For the determination of concentrations of substances with maximal optical densities for radiation of wavelengths 254, 297, 313, 365, 405 mμ it is preferable to use the lamp SVD-120A; for the remaining parts of the ultraviolet spectrum from 200–400 mμ the xenon gas discharge lamps DKSSh-200 give greater possibility of separating parts of the spectrum during operation with interference filters.
One should draw attention to the stabilization of radiation sources, since instability of radiation, especially with respect to the intensity of the spectral components, can lead to considerable difficulties in operation.
