Abstract
A significant reduction in measurable absorbance is demonstrated by ap plication of a wavelength modulation technique using diode lasers in l aser atomic absorption spectrometry in graphite tube atomizers. While rubidium and lanthanum are measured by absorption of fundamental diode laser radiation at 780.03 and 670.95 nm from the ground and an excite d state, respectively, aluminium is determined by deep blue light at 3 96.15 nm produced by the second harmonic generation of diode laser rad iation in an LiIO3 crystal.
