Abstract
Little consideration has been given of recent date to the possibilities of high frequency excitation with emission spectrography. By such excitation it is possible to make spectrographic investigations for elements in non-conducting materials and to investigate organic compounds which have the property of luminescing. High frequency excitation by means of a Tesla coil has been investigated in Europe but little in this country. Gerlach and Gerlach1 tried incorporating a Tesla coil with an oscillating circuit fed from a transmitting valve, but shelved this arrangement because of undesirable features such as sensitive tuning, nitrogen bands and lack of high voltage. An open high voltage spark which possessed the bad features of noise and shielding was preferred to drive the Tesla coil.
