Abstract
Atomic emission of lithium in a small graphite furnace (CRA 63) was observed using a standard atomic absorption spectrometer with simple optical modifications. Improved diagnostic techniques facilitated a study of lithium atomic emission and atomic absorption signal profiles as a function of temperature. Low levels of lithium were measured relatively free from background emission with considerably improved signal-to-noise characteristics. Analytical growth curves plotted in logarithmic coordinates showed only a slight deviation from linearity over a concentration range of three orders.
