1. An Interlaboratory Investigation of the Effect of Material Granularity and Sample Processing on Measurement Variability: Nutritional Elements in Cereals
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7927
Topic: Inorganic Analytical Chemistry
Published: 5/9/2013
Authors: Katrice A Lippa, Laura J Wood, Stefan D Leigh, Nathanael A Heckert
Abstract: This interlaboratory study was uniquely designed to determine the effects of material granularity and sample processing techniques on the measurement variability (i.e. precision) of nutritional elements in various cereal materials. Participants w ...

2. Recognizing and Overcoming Analytical Error in the Use of ICP-MS for the Determination of Cadmium in Nutraceuticals
Topic: Inorganic Analytical Chemistry
Published: 3/13/2013
Authors: Karen E Murphy, Thomas W Vetter
Abstract: The potential effect of spectral interference on the accurate measurement of the cadmium (Cd) mass fraction in nutraceutical materials using inductively coupled plasma quadrupole mass spectrometry was studied. The materials were two new Standard Refe ...

3. Fast standard addition method for LA-ICPMS using a spinning platform
Topic: Inorganic Analytical Chemistry
Published: 2/19/2013
Authors: John L Molloy, Stephen E Long, Fanny Claverie, Julian Malherbe, Naomi Bier
Abstract: A method has been developed for the fast and easy determination of Pb, Sr, Ba, Ni, Cu, and Zn, which are of geological and environmental interest, in solid samples by Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICPMS) using a samp ...

4. Certification of NIST SRM 2569 Lead Paint Films for Children's Products
Topic: Inorganic Analytical Chemistry
Published: 10/15/2012
Authors: John L Molloy, John R Sieber, Karen E Murphy, Stephen E Long, Stefan D Leigh
Abstract: SRM 2569 Lead Paint Films for Children’s Products is a new Standard Reference Material (SRM) developed for use primarily with XRF instrumentation. It consists of three paint coatings, with nominally 0 mg/kg, 90 mg/kg, and 300 mg/kg of Pb added, on p ...

5. Pilot Estuarine Mesocosm Study on the Environmental Fate of Silver Nanomaterials Leached from Consumer Products
Topic: Inorganic Analytical Chemistry
Published: 1/10/2012
Authors: Danielle Cleveland, Stephen E Long, Paul L. Pennington, Emily Cooper, Michael H. Fulton, Geoffrey I. Scott, Elijah J Petersen, Timothy M Brewer, Jeffrey M Davis, Laura J Wood
Abstract: Although nanosilver consumer products (CPs) now enjoy widespread availability, little work has been done to determine the environmental fate and leaching of silver nanoparticles (AgNPs) from these products. This type of work is crucial, since the lif ...

6. Predictive Gold Nanocluster Formation Controlled by Metal-Ligand Complexes
Topic: Inorganic Analytical Chemistry
Published: 1/9/2012
Authors: John M. Pettibone, Jeffrey W Hudgens
Abstract: The formation of ligand-protected transition metal nanoclusters in size-selective syntheses is driven by the inherent properties of the protecting ligands. We have previously reported the selective, monodisperse product formation of phosphine protect ...

7. Chromatographic Sample Collection from Two Phase (gas + liquid) Flows
Topic: Inorganic Analytical Chemistry
Published: 10/12/2011
Authors: Thomas J Bruno, Bret Windom
Abstract: A particularly challenging sample presentation in analytical chemistry is a flowing stream that consists of both a gas and liquid phase, in the situation in which an analysis is needed for both phases, separately. In these cases, the vapor and liqui ...

8. Measuring silver nanoparticle dissolution in complex biological and environmental matrices using UV-Visible absorbance
Topic: Inorganic Analytical Chemistry
Published: 8/2/2011
Authors: Justin M Zook, Stephen E Long, Danielle Cleveland, Carly Lay Geronimo, Robert I MacCuspie
Abstract: Distinguishing the toxic effects of nanoparticles (NPs) themselves from the well-studied toxic effects of their ions is a critical but challenging measurement for nanotoxicity studies and regulation. This measurement is especially difficult for silv ...

9. Achieving 0.2 % Relative Expanded Uncertainty in Ion Chromatography Analysis using a High-Performance Methodology
Topic: Inorganic Analytical Chemistry
Published: 4/12/2011
Authors: Ryan G. Brennan, Therese A. Butler, Michael R Winchester
Abstract: A high-performance (HP) technique that was originally developed for inductively coupled plasma optical emission spectrometry (ICP-OES) has been successfully translated to ion chromatography (IC) to enable analyses with extremely low uncertainty. As ...

10. Characterization and Purification of Commercial SPS and MPS by Ion Chromatography and Mass Spectrometry
Topic: Inorganic Analytical Chemistry
Published: 1/21/2011
Authors: Ryan G. Brennan, Melissa Meaney Phillips, Liang Yueh Ou Yang, Thomas P Moffat
Abstract: SPS (bis-(3-sulfopropyl) disulfide) is an essential electrolyte additive used in the fabrication of copper interconnects by electrodeposition. The process is used over length scales ranging from on-chip Damascene wiring to through-silicon-vias for c ...
