Abstract
A method of generating an electrical discharge in a high pressure gas contained in a sealed enclosure. The method includes driving a helical coil resonator at an RF frequency to generate an RF electric-magnetic field sufficient to generate an electrical discharge in the high pressure gas. The electrical discharge produces an emission spectrum that may be spectroscopically analyzed to determine the composition and impurity content of the gas.
