ABSTRACT:
Apparatus for analysing elements by inductive plasma spectrometry produced by the air. It comprises a tube, means for producing within said tube a plasma containing the element and means for the spectrometric analysis of the like from the plasma. The plasma production means incorporate means for circulating air in the tube, said air serving to produce the plasma. Application to the analysis of an element contained in the air.
