ABSTRACT:
A workpiece is positioned in contact with a contact electrode and spaced by a gap from a counter electrode. A unipolar electrical pulse is passed across this gap during a first time period. Thereafter during a second time period the light from the spark drawn across the gap is diffracted into a spectrum having lines corresponding to a plurality of the components of the workpiece and these lines are transformed into respective electrical signals having intensities corresponding to the concentrations of the respective components in the workpiece. During this second period the pulse continues to pass across the gap and the signals are integrated. At the start of a third period the pulse is stopped and then the integrated signals are compared with respective reference signals and error signals are generated in the case of any variance between the two. Multivibrators with respective time constants and connected in a chain control the function of relay switches for establishing these operations in these time periods.
