| Abstract: | In this paper, a new pulsed sampling apparatus is described that can be used to determine Na and K in ores by flame atomic absorption spectrome-try. The apparatus can also be used for the conventional technique. Compared with the latter method, the pulsed method has the advantages of using a smaller sampling volume and giving a better analytical precision at a higher throughput speed. |
