Creator:: Reid, Richard Donald
Abstract:: A nonflame method for atomic absorption spectroscopy is described. A helical tungsten filament from a commercially available 6-V, 4-A light bulb, heated to :incandescence in an argon atmosphere is used to atomize 2-μl aqueous samples for metals analyses. Studies of two hollow cathode lamp tungsten filament orientations, a modulated light...

Creator:: Manabe, Ronald M.
Abstract:: Investigations of plasma production by a pulsed dye laser microprobe were made. Comparisons between a Q- switched and a pulsed dye laser system were made on the intensity of the continuum produced by atmospheric breakdown. The dye laser system was foundtominimize the production of the continuum which in turn allowed...

Creator:: Beenen, Gerhard Joseph
Abstract:: The temporal and spatial characteristics of a laser microprobe plume were investigated using the spectroscopic methods of emission, absorption and fluorescence. The plume was produced by rapid vaporization of a small quantity (1 μg) of a solid sample using a focussed pulsed dye laser (110 MW/cm²). For absorption and fluorescence...

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)...

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...
