Abstract
In this paper we report a method and experiment system developed by us to useful for temporal and spatial temperature distribution of the flame for atomic obsorption spectroscopy in detail. The method and system principle is based on the modified sodium line reversal method. The studies on temporal (20–50 μsec range) and spatial (π 1mm) resolution of the flame temperature aim at establishing optimum analysis conditions and improving analysis characteristics of flame atomic absorption/emission spectroscopy.
