Improved Liquid Chromatography Methods for the Separation and Quantification of Biotin in Multivitamin/Multielement Tablets

April 24, 2006

Author(s)

B C. Nelson, Katherine E. Sharpless, Lane C. Sander

Two independently developed liquid chromatography (LC) methods for the quantitative determination of biotin in multivitamin/multielement tablets (NIST Standard Reference Material 3280 (SRM 3280)) are described. The methods use distinctly different tablet

Conformational Temperature Dependence of a Poly(ethylene-co-acrylic acid) Stationary Phase Investigated by Nuclear Magnetic Resonance Spectroscopy and Liquid Chromatography

April 1, 2006

C. Meyer, O. Pascui, D. Reichert, Lane C. Sander, Stephen Wise, K. Albert

Dietary Supplement Standard Reference Materials

March 27, 2006

Author(s)

Lane C. Sander, Katherine E. Sharpless, Stephen A. Wise

A new category of Standard Reference Materials based on dietary supplements are under development by NIST, with certified values for organic constituents and selected trace elements. These materials are provided primarily for use in method development and

Molecular Dynamics Simulations of Alkylsilane Stationary Phase Order and Disorder. 1. Effects of Surface Coverage and Bonding Chemistry

December 1, 2005

Author(s)

Katrice A. Lippa, Lane C. Sander, Raymond D. Mountain

Shape-selective polymeric alkylsilane stationary phases are routinely employed over the more common monomeric phases in reversed-phase liquid chromatography (RPLC) to improve the separation of geometric isomers of shape-constrained solutes. We have

Molecular Dynamics Simulations of Alkylsilane Stationary Phase Order and Disorder. 2. Effects of Temperature and Chain Length

December 1, 2005

Author(s)

Katrice A. Lippa, Lane C. Sander, Raymond D. Mountain

In an effort to elucidate the molecular-level structural features that control shape-selective separations, we have investigated the molecular dynamics of chromatographic models that represent both monomeric and polymeric stationary phases with alkylsilane
