Abstract

Many excitation sources used in spectrographic analysis exhibit the phenomenon of selective volatilization. This phenomenon is often useful for lowering the detection limits of elements through time resolving the exposure. If the total burn of a sample takes about 2 min, a number of different spectra may be taken over this duration with the result that the lines of elements which are selectively volatilized for a fractional part of the burning period have reduced background with better signal to noise ratios, and lead to lower detection limits.
