Reversed-Flow Chromatographic Determination of Binary Diffusion Coefficients

September 19, 2011
Author(s)
William S. McGivern, Jeffrey A. Manion
A reversed-flow chromatographic apparatus for the measurement of binary diffusion coefficients is described. Hydrocarbons are detected using flame ionization detection, and inert species can be detected by thermal conductivity. We have measured the binary

Dietary Supplement Laboratory Quality Assurance Program: The First Five Exercises

August 17, 2011
Author(s)
Melissa M. Phillips, Catherine A. Rimmer, Laura J. Wood, Katrice A. Lippa, Katherine E. Sharpless, David L. Duewer, Lane C. Sander, J. M. Betz
The National Institute of Standards and Technology (NIST) has established a Dietary Supplement Quality Assurance Program (DSQAP) in collaboration with the National Institutes of Health (NIH) Office of Dietary Supplements (ODS). Program participants measure

STR Sequence Analysis for Characterizing Normal, Variant, and Null Alleles

August 1, 2011
Author(s)
Margaret C. Kline, Carolyn R. Steffen, John M. Butler, Amy Decker
DNA sequence variation is known to exist in and around the repeat region of short tandem repeat (STR) loci used in human identity testing. While the vast majority of STR alleles measured in forensic DNA laboratories worldwide type as "normal" alleles

In Situ Gas Phase Measurements During Metal Alkylamide Atomic Layer Deposition

July 12, 2011
Author(s)
James E. Maslar, William A. Kimes, Brent A. Sperling
Metal alkylamide compounds, such as tetrakis(ethylmethylamido) hafnium (TEMAH), represent a technologically important class of metalorganic precursors for the deposition of metal oxides and metal nitrides via atomic layer deposition (ALD) or chemical vapor

Rapid-Heating of Ionic Energetic Materials using a Micro-Differential Scanning Device

July 10, 2011
Author(s)
Nicholas W. Piekiel, Richard E. Cavicchi, Michael R. Zachariah
We employ a microcalorimeter device to study the thermal decomposition of organic energetic materials at very high heating rates. The compact size of this device enables rapid heating rates and sensitive detection of thermal loads from very small samples

Chapter 21 Calibration of Aerosol Instruments

July 5, 2011
Author(s)
Bean T. Chen, Robert A. Fletcher, Yung-Sung Cheng
This chapter reviews calibration techniques relevant to aerosol measurement devices, such as sizing instruments, condensation nuclei counters, and mass monitors. The generation methods for test aerosols and important parameters in instrument calibration
