ABSTRACT:
In analysing a sample by atomic absorption or atomic fluorescence spectroscopy, the cloud of free atoms which interact with incident radiation is produced by heating a graphite body, disposed below the interaction region, on which the sample has been deposited. The body is heated in an inert atmosphere by passing electric current through it. Compact forms of apparatus which may replace the burner system of a conventional spectrometer utilise a horizontally disposed graphite rod around which flows a stream of inert gas.
