摘要：

A tungsten-tube atomizer has been developed and tested for a number of elements. The atomizer can be accommodated in the support of a commercial Varian carbon rod atomizer (CRA-63 or CRA-90) and operated as an alternative to the graphite tubes and cups. Characteristic concentrations, detection limits, optimum atomization temperatures, reproducibility and profiles of calibration curves obtained for Ag, Al, Ba, Cd, Co, Cu, Mg, Mn, Ni, Pb and V are similar to those obtained with the graphite-tube atomizer. The main advantage of this atomizer is its simple construction, low cost, long lifetime and excellent analytical performance, particularly for elements forming refractory carbides. © 1979.
