A Peruzzi, J. van Geel, A. Uytun, M. Kalemci, E. Uysal, Gregory F. Strouse, Yoana Y. Nuevo Ordonez, William Davis
Water triple point cells are the basis for the definition of the Kelvin and for the realization of the International Temperature Scale of 1990. The temperature differences between the cells are mainly caused by impurities arising in the cell water from the

Certification of Total Arsenic in Blood and Urine Standard Reference Materials by Radiochemical Neutron Activation Analysis and Inductively Coupled Plasma Mass Spectrometry

March 1, 2014
Author(s)
Rick L. Paul, William C. Davis, Karen E. Murphy, Colleen E. Bryan Sallee, Lee L. Yu, William F. Guthrie, Dennis D. Leber, Thomas W. Vetter
A newly developed procedure for determination of arsenic by radiochemical neutron activation analysis was used to measure arsenic in SRM 955c Toxic Elements in Caprine Blood and SRM 2668 Toxic Elements in Frozen Human Urine for the purpose of providing

Quantification of total serum transferrin and transferrin sialoforms in human serum; an alternative method for the determination of carbohydrate-deficient transferrin in clinical samples

January 20, 2014
Author(s)
Yoana Y. Nuevo Ordonez, William C. Davis, Raymond F. Anton
Carbohydrate deficient transferrin (CDT) measurements in human serum constitute the most specific marker for chronic heavy alcohol use and congenital disorders of glycosylation in proteins. Therefore, the development of precise and accurate analytical

Characterization of Perchlorate in a New Frozen Human Urine Standard Reference Material

October 1, 2012
Author(s)
Lee L. Yu, William C. Davis, Rabia Oflaz, Gregory C. Turk, Jeff M. Jarrett, Liza Valentin, Benjamin C. Blount, Dennis D. Leber, Eric L. Kilpatrick
Perchlorate, an inorganic anion, has recently been recognized as an environmental contaminant by the U.S. Environmental Protection Agency (EPA). Assessment of human exposure to perchlorate requires measurement of the anion in urine. Although the

Influence of mercury and selenium chemistries on the progression of cardiomyopathy in pygmy sperm whales, Kogia breviceps

October 1, 2012
Author(s)
Colleen E. Bryan Sallee, William C. Davis, Wayne E. McFee, Carola A. Neumann, Jennifer Schulte, Gregory D. Bossart, Steven J. Christopher
More than half of pygmy sperm whales (Kogia breviceps) that strand exhibit signs of cardiomyopathy (CMP). Many factors may contribute to the development of idiopathic CMP in K. breviceps, including genetics, infectious agents, contaminants, biotoxins, and

EVALUATION OF A MICROWAVE-ASSISTED METAL-LABELING STRATEGY FOR QUANTIFICATION OF PEPTIDES VIA RPLC-ICP-MS AND THE METHOD OF STANDARD ADDITIONS

November 26, 2011
