Abstract

An algorithm for the mathematical treatment of the sequence of time-resolved atomic emission spectra intended for separation of weak scintillations (flashes) of the analytical lines from noises and, as a consequence, for lowering the detection limits of the analyte elements is presented. It is shown that the application of the algorithm leads to a more than twofold increase in the signal-to-noise ratio in the time dependence graph of the intensity of an analytical peak of the analyte element. The algorithm is incorporated into the Atom Program.
