Cold vapor atomic absorption and fluorescence analysis of mercury

Creator:: Hawley, James Edward
Abstract:: A critical study of the cold vapor atomic absorption and fluorescence instrumentation for the analysis of mercury is described. Some of the important modifications involve the reduction vessel, absorption cell, fluorescence cell, and radiation source. The new modified systems have much greater calibration sensitivities and lower detection limits than those...

Sample entraining multi-electrode plasma sources for atomic emission spectroscopy

Creator:: Lee, Gae Ho
Abstract:: Plasma sources with multiple electrodes have been developed and characterized in this research for atomic emission spectroscopy. Multi-electrode plasma sources use electrodes to shape the plasma in order to continuously entrain a sample stream in the center of hot plasma, in a manner similar to an inductively coupled plasma (ICP)...

An atmospheric pressure glow discharge detector for capillary column gas chromatography

Creator:: Baur, Susanna S.
Abstract:: The change in the oscillation frequency in the current of an atmospheric helium glow discharge is a sensitive detector for gas chromatography. The response of the detector is in the femtomole and picomole range for nonane and decane. The effluent of a capillary column is directed into a glow discharge...

Fundamental studies of a gas-jet enhanced sputtering system and its applications

Creator:: Kim, Hyo-jin
Abstract:: The use of gas jets in a sputtering cell makes this direct sampling method practical for atomic absorption and mass spectrometry determinations. With a commercial six-jet sputtering source, the Atomsource (Analyte Corp., Grants Pass, Oregon), that directly atomizes solid samples for conventional atomic absorption spectrophotometers, the sample loss rate for...

A new glow discharge detector for carbohydrates in aqueous chromatography

Creator:: Herring, Christopher Jackson
Abstract:: An atmospheric pressure argon glow discharge is shown to detect trace levels of carbohydrates in aqueous flowing systems, using either of two glow discharge solution interface configurations. The first configuration consists of an oscillating glow discharge sustained between a flowing aqueous cathode and platinum anode. Picomole and micromolar mass and...

Studies of glow discharge oscillations and jet-enhanced cathodic sputtering

Creator:: Zhu, Zhubiao
Abstract:: Three aspects of glow discharges have been studied: glow discharge oscillations, sputtering, and coupling between cathode and anode regions the two most important regions in a glow discharge. Cathode and anode processes are tightly coupled by electron and ion coupling effects. Both electron and ion coupling effects were observed by...

Investigation of the relationships between laser energy and vaporized target material, continuum intensity, and plume energy in laser plume spectroscopy

Creator:: Flugstad, Paul Morris
Abstract:: A focused Q-switched neodymium-doped glass laser with power levels ranging from 1-6 MW and with a 50-nsec halfwidth, was used to vaporize copper metal. Experimental measurements showed that the amount of material vaporized away from the target was not linear with laser power and was much less than could be...
