Using a simple rate equation model, the laser power density Ic necessary to reach 50% of the saturation limited population of the excited atomic level under typical flame conditions is calculated. For Na atoms aspirated into the flame a saturating power density for irradiation with a narrow dye laser line (bandwidth 0.033 Å) of Ic ~ 0.4 kW/cm2 was determined. With the aid of a dye laser with an appropriate laser power density, analytical curves for Na were measured yielding a detection limit of 0.2 ng/ml. This sensitivity is comparable with the best results obtained by atomic emission flame spectrometry.

Flame Spectrometry

A Fortran program was written to calculate the approximate total half-intensity linewidths of several spectral lines for a number of atoms in some common analytical flames. By means of this program, total half-intensity linewidths of any atomic spectral line can be calculated if sufficient spectral and flame compositional data are available. Calculations have been made for 136 lines of 60 elements, and the data have been tabulated.
