ABSTRACT:
Improvements on a DC plasma jet generator for emission spectrochemical analysis wherein two anode blocks and one cathode block are positioned in an inverted Y shape, and each of the anode blocks has a cylinder, a piston, an an anode received by a recess in the end of the piston. Each anode can be secured in the recess at the end of the piston in the corresponding anode block by magnetic force. Each of the anode and cathode blocks is pivotable so that the associated electrode attached to each block can be fixed upright with the free end thereof directed upward. This means that the electrodes can be replaced easily as well as speedily by remote control using manipulators.
