Abstract
The potential of wavelength modulation laser atomic absorption spectro metry in analytical flames is demonstrated by the measurement of titan ium, cesium and chromium applying fundamental and frequency doubled ra diation of commercially available semiconductor diode lasers. In depen dence on the radiation power, absorbances of the order of 10(-4)-10(-6 ) are measured, which reveal very low detection limits even when weak absorption lines are used.
