Abstract:The high frequency ignited arc was described by Pfeilsticker in 1937. His purpose was to obtain a series of very short arc periods so that surface layers and very minute semples could be analyzed by the use of the d.c. arc. Hemmendinger used a similar circuit in his investigation on time effects in the d.c. arc, but did not describe its use in quantitative analysis. Brockman and Hockgesan described the use of such a circuit for the ignition of the d.c. arc in order to reduce background and to more accurately time the arcing period. Saunderson an Caldecourt used this system to insure prompt and unfailing ignition of the otherwise conventional a.c. arc when using electrodes which maintain the arc in an uncertain manner.
