Three new, glow discharge devices have been designed and investigated. The new devices were made to improve the measurement precision of solution residues. An improvement in the precision would allow the glow discharge to be more fully exploited as an excitation source. / The first device constructed operated at atmospheric pressure. Detection limits are reported for Cu, Na, Sr, and In. / The second device described is a low pressure device for discrete samples. The detection limits for Cu, V, In, and Co are comparable to those obtained with demountable hollow cathode lamps, but with better precision. Rotational and excitation temperatures are examined as functions of fill gas pressure and discharge current. A sputtering constant is presented and the technique for measuring this parameter is described. / The third device described provides continuous sample introduction into a low pressure glow discharge. A chain conveyor is used for sample transport. Results are reported for aqueous Pb, Cd, B, and Cu sample solutions. Studies of sample volatility, matrix, and organic solvent effects are reported. The device is shown to possess many useful features. Its potential utility as an element selective detector for liquid chromatography is suggested. / Source: Dissertation Abstracts International, Volume: 43-09, Section: B, page: 2889. / Thesis (Ph.D.)--The Florida State University, 1982.
