Solid-state analytical characterization of electrochemically modified glassy carbon electrodes
Autor: Donald L. Dugger, Mark L. Bowers, Rosemary Wilson, Jesse Hefter
Publikováno v: Analytica Chimica Acta. 248:127-142
Glassy carbon electrodes were electrochemically modified in sulfate, phosphate and carbonate media (and attempts at modification were tried in perchlorate media) by cycling to high positive potentials, yielding electrodes capable of incorporating cat

Quantitative Determination of Er in Silica-Based Matrices
Autor: Mahendra P. Singh, T. Michael Wei, Francis Pink, Joseph Connolly, Daniel W. Oblas, Donald L. Dugger
Publikováno v: MRS Proceedings. 244
The distribution and concentration of dopants in the core of an optical fiber, at low concentrations, particularly the rare earth dopants, are difficult to measure quantitatively. However, such information is critical to the determination of absorpti

Trace determination of carbon and oxygen in tungsten by spark-source mass-spectrography
Autor: Daniel Oblas, Donald L. Dugger
Publikováno v: Talanta. 24:447-451
A high pumping-speed vacuum system, incorporating a mechanical cryo-pump, was designed and built to attach to the source of a spark-source mass-spectrometer to reduce the partial pressure of carbon- and oxygen-containing gases. Pressures in the 10(-1

Metastable Transitions Observed in a Time‐of‐Flight Mass Spectrometer
Autor: Robert W. Kiser, Donald L. Dugger
Publikováno v: The Journal of Chemical Physics. 47:5054-5061
A time‐of‐flight mass spectrometer has been employed in the investigation of metastable transitions by using a retarding potential technique. Expressions have been developed which permit a simple, nearly quantitative determination of the masses o

Modification of an SSMS ion source to reduce residual gas effects
Autor: Donald L. Dugger, Daniel W. Oblas
Publikováno v: Journal of Vacuum Science and Technology. 17:826-828
A simple modification to the spark shield of the ion source of a spark source mass spectrograph is discussed. This helps to maintain a low partial pressure of residual gases during sparking of reactive materials. A grid is placed over the viewing sli
