Abstract

The use of a hollow electrode form with the employment of a gas stream to introduce a sample into a spectral excitation column is discussed. Three uses are proposed: (1) the direct introduction into the excitation gap of contaminated gas samples such as dust-laden air, (2) the direct introduction of special atmospheres into an excitation column to utilize their effects on spectral excitation, (3) the gas transportation of atomized solutions into an excitation gap.
